Identification of hydroxyquinazoline alkaloids from Justicia adhatoda L. leaves, a traditional natural remedy with NF-κB and AP-1-mediated anti-inflammatory properties and antioxidant activity. JOURNAL OF ETHNOPHARMACOLOGY 2024; 331:118345. [PMID: 38754645 DOI: 10.1016/j.jep.2024.118345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 05/07/2024] [Accepted: 05/13/2024] [Indexed: 05/18/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Justicia adhatoda L. is used as traditional medicine in Nepal to treat cough, asthma, and inflammatory disorders, and is indicated as "Asuro". Leaves are used worldwide as herbal medicine due to cardiotonic, expectorant, anti-asthmatic, and bronchodilatory properties. The aim of this work was to study the phytochemical composition of leaves of Nepalese J. adhatoda and assess their anti-inflammatory and antioxidant properties in vitro. MATERIALS AND METHODS Secondary metabolites were extracted from dried leaves using methanol (JAME: J. adhatoda methanol extract). They were analysed by means of liquid chromatography coupled with multiple-stage mass spectrometry (LC-MSn). Anti-inflammatory potential was determined by the NF-κB and AP-1 inhibition assay, and DPPH, ABTS, and β-carotene bleaching assays were performed to assess its antioxidant properties. RESULTS JAME is a rich source of secondary metabolites, especially quinazoline alkaloids such as vasicine, vasicinone, vasicoline, and adhatodine. 7-Hydroxy derivatives of peganidine, vasicolinone, and adhatodine were also identified by means of MSn data and are here reported in J. adhatoda for the first time. JAME inhibited NF-κB and AP-1 expression in THP-1 cells to a greater extent than the positive control prednisolone. A moderate radical-quenching property was observed in DPPH and ABTS assays, but the anti-carotene bleaching activity was significantly higher than the reference BHT. CONCLUSIONS To the best of our knowledge, this is the first insight into the phytochemical composition of Asuro leaves from Nepal and their bioactivity. Our results will contribute to the valorisation of this medicinal species still widely used in the traditional and complementary medicine.

Abstract
This study characterized and identified the antimicrobial compounds from an endophytic fungus (Fusarium incarnatum (C4)) isolated from the orchid, Cymbidium sp. Chromatographic techniques were employed to separate the bioactive compounds from the crude extracts of F. incarnatum (C4). Following bio-guided fractionation, two fractionated extracts (fractions 1 and 2) of F. incarnatum (C4) exhibited antibacterial and antifungal activities against Bacillus cereus (MIC: 0.156 mg/mL) and Ganoderma boninense (MIC: 0.3125 mg/mL), respectively. The active fractions were discovered to comprise of a variety of bioactive compounds with pharmacological importance (alkaloids, flavonoids, phenolic compounds, terpenoids, peptides and fatty acids). Liquid chromatography mass-spectrometry (LCMS) analysis detected the presence of antibacterial (kanzonol N, rifaximin, linoleic acid (d4), cannabisativine, docosanedioic acid, and stearamide) and antifungal components (3-methyl-quinolin-2-ol, prothiocarb, kanzonol N, peganine, 5Z-tridecene, and tetronasin) in fractions 1 and 2, respectively, which may have contributed to the antimicrobial effects. Findings from this study highlighted the important potential of fungal endophytes from medicinal hosts as producers of antimicrobials and antibiotics.

Abstract
Medicinal plants are rich in secondary metabolites with beneficial pharmacological effects. The production of plant secondary metabolites is subjected to the influences by environmental factors including the plant-associated microbiome, which is crucial to the host's fitness and survival. As a result, research interests are increasing in exploiting microbial capacities for enhancing plant production of pharmacological metabolites. A growing body of recent research provides accumulating evidence in support of developing microbe-based tools for achieving this objective. This mini review presents brief summaries of recent studies on medicinal plants that demonstrate microbe-augmented production of pharmacological terpenoids, polyphenols, and alkaloids, followed by discussions on some key questions beyond the promising observations. Explicit molecular insights into the underlying mechanisms will enhance microbial applications for metabolic fortification in medicinal plants.

Abstract
Cinnamomum is the largest genus of Lauraceae family and has been used as spices, food, and food additives by the people. Total 15 Cinnamomum species are distributed in different parts of Indian sub-continent. Different parts (leaves, stem bark, stem wood, roots, flowers, and fruits) of these species were shade-dried and used for the determination of essential oils. A total of 19 essential oils were identified and quantified from the different parts of (leaf, stem bark, stem wood, root, flower, and fruit) of 15 Cinnamomum species. The stem bark of C. altissimum was rich in the presence of essential oils (52.2 %) whereas minimum levels of essential oils were recorded in roots (17.9 %). The γ-terpinene (11.1 %) was reported as the major component essential oil in C. subavenium flowers. Methanol extract of C. camphora stem wood showed stronger lowest minimum inhibitory concentration against S. aureus (25 ± 0.01 μg/ml), H. pylori (29 ± 0.05 μg/ml), B. subtilis (31 ± 0.03 μg/ml), E. faecalis (33 ± 0.01 μg/ml), C. albicans (38 ± 0.03 μg/ml) when compared to amoxycillin (S. aureus 56 ± 0.05 μg/ml; B. subtilis 27 ± 0.04 μg/ml, E. faecalis 22 ± 0.01 μg/ml), streptomycin (H. pylori 38 ± 0.02 μg/ml) and fluconazole (C. albicans 56 ± 0.01 μg/ml). Methanolic extract of C. camphora stem wood demonstrated maximum antimicrobial activity against S. aureus, H. pylori, B. subtilis, E. faecalis and C. albicans. The essential oil of C. altissimum stem bark displayed significant lowest MIC against S. aureus (21 ± 0.03 μg/ml), E. coli (22 ± 0.03 μg/ml), E. cloacae (37 ± 0.06 μg/ml), L. monocytogenes (47 ± 0.08 μg/ml), and P. chrysogenum (101 ± 0.07 μg/ml) when compared to amoxycillin (E. coli 18 ± 0.01 μg/ml, E. cloacae 21 ± 0.05 μg/ml, L. monocytogenes 31 ± 0.03 μg/ml), and fluconazole (P. chrysogenum 101 ± 0.07 μg/ml). The essential oil of C. altissimum stem bark displayed maximum antimicrobial activity against S. aureus, E. coli, E. cloacae, L. monocytogenes, and P. chrysogenum. Cinnamomum essential oils may be used as an alternative source of antibacterial and antifungal compounds in the treatment of various types of infections.

Abstract
Dengue fever has become a major public health concern. It is usually related to intravascular leaking, bleeding disorders, and thrombocytopenia and is recognized as a potent threat to humans. The scarcity of anti-dengue medication or vaccine for such a serious disease leads to an upsurge in the usage of traditional medicines for its proper management. India has diverse biodiversity and a long history of using plant-based remedies. Several medicinal plant extracts have been studied for producing anti-dengue viral activity. AYUSH traditional systems provide a plethora of plants that have been reported to be useful in the treatment of fever. Single and compound plant- based formulations in natural form have been used in Unani holistic approaches. This review serves as a new approach to illustrate the most recent evidence regarding the antiviral activity of various plants by providing scientific proof and also to validate the traditional formulations as effective treatments in dengue fever for global acceptance.

Abstract
Adhatoda vasica is used in the treatment of cold, cough, chronic bronchitis, asthma, diarrhea, and dysentery. The biological activities of this species are attributed with the presence of alkaloids, triterpenoids, and flavonoids. Agrobacterium rhizogenes-mediated transformation of A. vasica, produces pyrroloquinazoline alkaloids, was achieved by infecting leaf discs with strain ATCC15834. The bacterial strain infected 82.7% leaf discs and 5-7 hairy root initials were developed from the cut edges of leaf discs. In this study, seven strains of Azotobacter chroococcum and five strains of Pseudomonas putida were used for the biotization of hairy roots. Plant growth-promoting rhizobacteria (PGPR) develops symbiotic association with roots of plants and increases the growth parameters of plants. PGPR (A. chroococcum and P. putida) increased the profiles of nitrogenase and acid phosphatase enzymes, biomass, dry matter contents, anthranilate synthase activity and accumulation of pyrroloquizoline alkaloids in the biotized hairy roots. Both enzymes (nitrogenase and acid phosphatase) maintain sufficient supply of nitrogen and dissolved phosphorus to the cells of hairy roots therefore, the levels of anthranilate synthase activity and pyrroloquinazoline alkaloids are increased. Total seven pyrroloquinazoline alkaloids (vasicine, vasicinone, vasicine acetate, 2-acetyl benzyl amine, vasicinolone, deoxyvasicine and vasicol) were identified from the biotized hairy roots of A. vasica. In our study, biotization increased the profiles of pyrroloquinazoline alkaloids therefore, this strategy may be used in increasing the production of medicinally important secondary metabolites in other plant species also. Our hypothetical model demonstrates that P. putida cell surface receptors receive root exudates by attaching on hairy roots. After attachment, the bacterial strain penetrates in the biotized hairy roots. This endophytic interaction stimulates acid phosphatase activity in the cells of biotized hairy roots. The P. putida plasmid gene (ppp1) expression led to the synthesis of acid phosphatase in cytosol. The enzyme enhances phosphorus availability as well as induces the formation of phosphoribosyl diphosphate. Later, phosphoribosyl diphosphate metabolizes to tryptophan and finally tryptophan converts to anthranilic acid. The synthesized anthranilic acid used in the synthesis of alkaloids in A. vasica.

Abstract
Fetal hemoglobin (HbF) is a potent genetic modifier, and the γ-globin gene induction has proven to be a sustainable therapeutic approach for the management of β-thalassemia. In this study, we have evaluated the HbF induction ability of A. vasica in vitro and in vivo, and the identification of potential therapeutic compounds through a bioassay-guided approach. In vitro benzidine-Hb assay demonstrated strong erythroid differentiation of K562 cells by A. vasica extracts. Subsequently, an in vivo study with an aqueous extract of A. vasica (100 mg/kg) showed significant induction of the γ-globin gene and HbF production. While in the acute study, the hematological and biochemical indices were found to be unaltered at the lower dose of A. vasica. Following the bioassay-guided approach, two isolated compounds, vasicinol (1) and vasicine (2) strongly enhanced HbF levels and showed prominent cellular growth kinetics with ample accumulation of total hemoglobin in K562 cultures. High HbF levels were examined by immunofluorescence and flow cytometry analysis, concomitant with the overexpression in the γ-globin gene level. Compound 1 (0.1 µM) and compound 2 (1 µM) resulted in a greater increase in F-cells (90 and 83%) with marked up (8-fold and 5.1-fold) expression of the γ-globin gene, respectively. Molecular docking studies indicated strong binding affinities of (1) and (2) with HDAC2 and KDM1 protein that predict the possible mechanism of compounds in inhibition of these epigenetic regulators in the γ-globin gene reactivation. Altogether, these observations demonstrated the therapeutic usefulness of A. vasica for fostering HbF production in clinical implications for blood disorders.

Abstract
BACKGROUND AND AIM Balarista is a fermented ayurvedic liquid preparation recommended as a good therapy for the treatment of rheumatoid arthritis. In the present investigation, the anti-arthritic activity of in-house Balarista formulation and marketed M1, M2, M3 and M4 Balarista formulations at the dose of 2.31 ml/kg were studied on Complete Freund's adjuvant-induced arthritic rat model. EXPERIMENTAL PROCEDURE Measurement of paw diameter, arthritic index, arthritic score, and body weight were made to assess the anti-arthritic activity. Alterations in hematological and biochemical parameters were carried out to ascertain the disease progression. The inflammatory mediators (TNF-α, IL-1β, and IL-6) were measured by the ELISA method. The oxidative stress parameters were evaluated in tissues of joint, liver, spleen and kidney. The histological and radiological changes in the ankle joint of rats were also studied. RESULTS AND CONCLUSION Administration of in-house and marketed formulations exhibited significant anti-arthritic activity by reducing all the arthritic parameters. The anomalous alterations in hematological and biochemical parameters were remarkably restored. The expression level of serum pro-inflammatory cytokines was significantly suppressed in treated animals. The oxidative stress, indicated by an increase in lipid peroxidation, decreased in antioxidant enzyme i.e. superoxide dismutase and catalase along with non-enzymatic reduced glutathione in tissues, were strongly counteracted by the formulation. Abnormal changes in arthritic ankle joints shown by X-ray and histological examination were significantly protected by the formulation. The present study suggests that the administration of in-house and marketed Balarista formulations have produced a significant anti-arthritic effect by inhibiting free radicals and inflammatory cytokines.

Abstract
Eicosanoid pathways play a crucial role in the progression and resolution of inflammation. NSAIDs act as anti-inflammatory agents by inhibiting both the isoforms of cyclooxygenases (COXs) whereas, COXIBs act as specific COX-2 inhibitors. Excessive usage of the same is linked with gastrointestinal bleeding and increased cardiovascular risk, respectively. The current in-silico study was aimed at evaluating the potential of major alkaloids of A. vasica (vasicine (VAS), vasicinone (VAE), and Deoxyvasicine (DOV)) as inhibitors of COXs. The results of the computed binding energy (ΔG) indicate that Celecoxib (CEL), DOV, and VAS have a higher affinity to COX-2, while VAE has a higher affinity to COX-1, and Mefenamic acid (MEF) was not selective. Among the alkaloids, VAE exhibited the best ΔG (of -8.2 kcal/mol) with COX-1, while VAS exhibited the best ΔG (of -8.2 kcal/mol) with COX-2. This was comparable to the ΔG exhibited by Mefenamic acid (-8.7 kcal/mol with both the COXs). With their potential to remain gastroprotective while having the ability to inhibit enzymes of both the prostaglandin and leukotriene pathways, the alkaloids of A. vasica could be promising leads for the design of Eicosanoid pathway modulators/inhibitors.Communicated by Ramaswamy H. Sarma.

Abstract
Inflammation is an adaptive response of the immune system to tissue malfunction or homeostatic imbalance. Corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) are frequently applied to treat varieties of inflammatory diseases but are associated with gastrointestinal, cardiovascular, and kidney side effects. Developing more effective and less toxic agents remain a challenge for pharmaceutical chemist due to the complexity of the different inflammatory processes. Alkaloids are widely distributed in plants with diverse anti-inflammatory activities, providing various potential lead compounds or candidates for the design and discovery of new anti-inflammatory drug candidates. Therefore, re-examining the anti-inflammatory alkaloid natural products is advisable, bringing more opportunities. In this review, we summarized and described the recent advances of natural alkaloids with anti-inflammatory activities and possible mechanisms in the period from 2009 to 2020. It is hoped that this review of anti-inflammatory alkaloids can provide new ideas for researchers engaged in the related fields and potential lead compounds for the discovery of anti-inflammatory drugs.

Abstract
Mitochondrial dysfunction and disturbed mitochondrial dynamics were found to be common phenomena in the pathogenesis of Parkinson's disease (PD). Vasicinone is a quinazoline alkaloid from Adhatoda vasica. Here, we investigated the autophagy/mitophagy-enhancing effect of vasicinone and explored its neuroprotective mechanism in paraquat-mimic PD modal in SH-SY5Y cells. Vasicinone rescued the paraquat-induced loss of cell viability and mitochondrial membrane potential. Subsequently, the accumulation of mitochondrial reactive oxygen species (ROS) was balanced by an increase in the expression of antioxidant enzymes. Furthermore, vasicinone restored paraquat-impaired autophagy and mitophagy regulators DJ-1, PINK-1 and Parkin in SH-SY5Y cells. The vasicinone mediated autophagy pathways were abrogated by treatment with the autophagy inhibitor 3-MA, which lead to increases α-synuclein accumulation and decreased the expression of p-ULK and ATG proteins and the autophagy marker LC3-II compared to that observed without 3-MA treatment. These results demonstrated that vasicinone exerted neuroprotective effects by upregulating autophagy and PINK-1/Parkin mediated mitophagy in SH-SY5Y cells.

Abstract
Many herbal agents and medicinal plants have provided clinical interest due to their therapeutic properties, availability and lower side effects. The aim of this study was to understand the anti-bacterial activity of the combination of Pelargonium sidoides (PEL), Justicia adhatoda (ADH) and N-Acetyl-L-Cysteine (NAC) (NAXX). We found that NAXX had strong and long-term bacteriostatic activity, which was related to its anti-oxidant activity. Our data demonstrate that NAXX is an innovative medicinal plant-derived strategy to manage of oxidative stress- and microbial-based diseases.

Abstract
Background Myocardial infarction is the leading cause of damage to the heart and is classified as a major cause of death related to cardiovascular disease. In the present study, we intended to investigate the protective effect of vasicine (VAS) against myocardial infarction in rats, and its mechanism. Methods Myocardial infarction was induced by isoproterenol (ISO, 100 mg/kg) at an interval of 24 h for 2 days. Different doses of VAS (2.5, 5, and 10 mg/kg body weight) were administered to the rats. The effect of VAS on oxidative stress markers such as, myocardial necrosis, myocardial ability and infarct volume, inflammatory cytokines, membrane-bound myocardial enzymes, and histopathological changes was investigated. Western blot analysis was also conducted to analyze the effect of VAS on autophagy (PI3K/Akt) and apoptosis (Bcl-2, Bax, and caspase-3). The number of apoptotic cells in the different groups was also identified using TUNEL. Results Results suggested that VAS causes reduction in myocardial necrosis by reduction of elevated LDH, CK-MB, and TnT levels. It also causes augmentation of left ventricular systolic pressure (LVSP) and myocardial contractility as determined in terms of +dp/dtmax and –dp/dtmax. Furthermore, VAS causes reduction of TNF-α and IL-6 levels. VAS also improved cardiac function via enhancing posterior wall thickness of the LV with concurrent increase in the mass of LV. In the present study, VAS caused activation of phosphorylated PI3K (p-PI3K) and phosphorylated Akt (p-Akt) in a dose-dependent manner. Furthermore, VAS suppressed apoptosis when tested on animals suffering from ISO-induced MI, by decreasing the expression of cleaved Caspase-3 and Bax while increasing the expression of Bcl-2. Conclusion In conclusion, vasicine has a protective effect against MI in vivo, through inhibiting oxidative stress, inflammation and excessive autophagy, to suppress apoptosis via activation of the PI3K/Akt/mTOR signaling pathway.

Abstract
Vasicinone is a quinazoline alkaloid isolated from the Adhatoda vasica plant. In this study, we explored the neuroprotective effect and underlying molecular mechanism of vasicinone against paraquat-induced cellular apoptosis in SH-SY5Y cells. Vasicinone reduced the paraquat-induced loss of cell viability, rescued terminal deoxynucleotide transferase-mediated dUTP nick end-labeling (TUNEL)-positive apoptotic nuclei, and suppressed generation of reactive oxygen species (ROS) in a dose-dependent manner. Western blotting analysis revealed that vasicinone increased the phosphorylation of IGF1R/PI3K/AKT cell survival signaling molecules and downregulated the paraquat-induced, mitogen-activated protein kinase (MAPK)/c-Jun N-terminal kinase (JNK)-mediated apoptotic pathways compared to that observed in cells not treated with vasicinone. This protection depended critically on the activation of IGF1R, and the silencing of IGF1R by siRNA completely abrogated the protective effect of vasicinone in SH-SY5Y cells. Our findings indicated that vasicinone is a potential candidate for the treatment of Parkinson’s disease and possibly other oxidative stress-related neurodegenerative disorders.

Abstract
<P>Background: A considerable worldwide increase in the rate of invasive fungal infections
and resistance toward antifungal drugs was witnessed during the past few decades. Therefore, the need
for newer antifungal candidates is paramount. Nature has been the core source of therapeutics for thousands
of years, and an impressive number of modern drugs including antifungals were derived from
natural sources. In order to facilitate the recognition of potential candidates that can be derived from
natural sources, an iterative stochastic elimination optimization technique to index natural products for
their antifungal activity was utilized.
Methods:
A set of 240 FDA-approved antifungal drugs, which represent the active domain, and a set of
2,892 natural products, which represent the inactive domain, were used to construct predictive models
and to index natural products for their antifungal bioactivity. The area under the curve for the produced
predictive model was 0.89. When applying it to a database that is composed of active/inactive chemicals,
we succeeded to detect 42% of the actives (antifungal drugs) in the top one percent of the screened
chemicals, compared with one-percent when using a random model.
Results and Conclusion:
Eight natural products, which were highly scored as likely antifungal drugs,
are disclosed. Searching PubMed showed only one molecule (Flindersine) out of the eight that have
been tested was reported as an antifungal. The other seven phytochemicals await evaluation for their
antifungal bioactivity in a wet laboratory.</P>

Abstract
Vasicinone, a quinazoline alkaloid from Adhatoda vasica Nees. is well known for its bronchodilator activity. However its antiproliferative activities is yet to be elucidated. Here-in we investigated the anti-proliferative effect of vasicinone and its underlying mechanism against A549 lung carcinoma cells. The A549 cells upon treatment with various doses of vasicinone (10, 30, 50, 70 µM) for 72 h showed significant decrease in cell viability. Vasicinone treatment also showed DNA fragmentation, LDH leakage, and disruption of mitochondrial potential, and lower wound healing ability in A549 cells. The Annexin V/PI staining showed disrupted plasma membrane integrity and permeability of PI in treated cells. Moreover vasicinone treatment also lead to down regulation of Bcl-2, Fas death receptor and up regulation of PARP, BAD and cytochrome c, suggesting the anti-proliferative nature of vasicinone which mediated apoptosis through both Fas death receptors as well as Bcl-2 regulated signaling. Furthermore, our preliminary studies with vasicinone treatment also showed to lower the ROS levels in A549 cells and have potential free radical scavenging (DPPH, Hydroxyl) activity and ferric reducing power in cell free systems. Thus combining all, vasicinone may be used to develop a new therapeutic agent against oxidative stress induced lung cancer.

Abstract
Pyrroloquinazoline alkaloids are medicinally important compounds, determined by HPLC from cell cultures of Adhatoda vasica . The maximum production of vasicinone (12-fold) and vasicine (8.3-fold) was enhanced by stimulating the anthranilate synthase activity via feeding of tryptophan and sorbitol. The decoction of Adhatoda vasica leaves is used for the treatment of throat irritations, inflammations and recommended as expectorant. The plant species contains pyrroloquinazoline alkaloids and has been reported to demonstrate various biological activities. To investigate the effect of elicitors to increase the production of alkaloids, five groups (auxins and cytokinins, biotic elicitors, polysaccharides, amino acids and salts) of elicitors were evaluated. Maximum production of vasicinone (72.74 ± 0.74 mg/g DW; 12-fold) and vasicine (99.44 ± 0.28 mg/g DW; 8.3-fold) was enhanced by feeding of tryptophan and sorbitol at 50 mM concentration in cell cultures. Fourteen free amino acids were estimated from the elicited cells. Sorbitol stimulated up to a maximum accumulation of serine (8.2-fold). The maximal anthranilate synthase (AS) activity (7.5 ± 0.47 pkat/mg protein; 2.9-fold) was induced by salicylic acid and sorbitol. Anthranilate synthase functions as rate-limiting factor for the biosynthesis of pyrroloquinazoline alkaloids. Our results support the widespread use of tryptophan and sorbitol as elicitors to raise the production of vasicinone, vasicine, 2-acetyl benzyl amine and other pyrroloquinazoline alkaloids in cell cultures of A. vasica.

Antitussive effect of a fixed combination of Justicia adhatoda, Echinacea purpurea and Eleutherococcus senticosus extracts in patients with acute upper respiratory tract infection: A comparative, randomized, double-blind, placebo-controlled study. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2015; 22:1195-1200. [PMID: 26598919 DOI: 10.1016/j.phymed.2015.10.001] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Revised: 10/02/2015] [Accepted: 10/04/2015] [Indexed: 06/05/2023]
Abstract
BACKGROUND Kan Jang® oral solution (KJ) is a fixed combination of aqueous ethanolic extracts of Justicia adhatoda L. leaf, Echinacea purpurea (L.) Moench root, and Eleutherococcus senticosus (Rupr. & Maxim.) Harms root. It is approved in Scandinavia as an herbal medicinal product for respiratory tract infection treatment. PURPOSE The present clinical trial aimed to compare the antitussive effect of KJ with placebo (PL) and bromhexine (BH) among patients of 18-65 years old with non-complicated upper respiratory infections (URI; i.e., common cold). STUDY DESIGN We performed a parallel-group, randomized, double-blinded, placebo-controlled trial in in 177 patients with acute URI over a 5 day period. METHODS We investigated the antitussive effects of a KJ (30 ml/day; 762 mg genuine extracts with standardized contents of 0.2 mg/ml vasicine, 0.8 mg/ml chicoric acid, and 0.03 mg/ml eleutherosides B and E), bromhexine hydrochloride (24 mg/30 ml/day) and PL on cough and blood markers. The primary outcome was cough relief, which was assessed as the change of cough frequency from baseline (cough index). Secondary outcomes were safety with regards to reported adverse events (AEs) and hematological data. RESULTS Both KJ and BH relieved cough more effectively than placebo. On the third and fourth days of treatment, we observed faster improvement in the group receiving KJ compared to in the groups receiving BH (100%) or PL (100%), indicating a slightly shorter recovery time in the KJ group. KJ showed a good tolerability and safety profile. CONCLUSION KJ exerted significant antitussive effects in URI. The present data further support the therapeutic use of KJ in upper respiratory tract infections.

Abstract
Adhatoda zeylanica is a dietary supplement ingredient present in several types of dietary supplements, including weight loss, respiratory relief, and immune regulating products. Due to its reported wide range of uses in folk medicine, it was hypothesized that it may have the potential to target multiple organs and lead to a range of toxicity features. As a preliminary evaluation of the safety of this herbal ingredient, an investigation into its effects on the kidney was sought. An in vitro study of its potential nephrotoxicity using the HK-2 human proximal tubule cell line in a variety of functional indicators was performed to capture both general forms of cellular toxicity as well as ones that are specific to proximal tubules. A. zeylanica was only capable of inducing detrimental short-term toxicity to HK-2 cells at relatively high treatment concentrations when exposed directly to the cells. The lack of acute and potent toxicity of A. zeylanica under our experimental conditions calls for further studies to better define its toxicant threshold and establish safe dosage levels.

Abstract
INTRODUCTION Quinazoline is one of the most studied moieties in medicinal chemistry due to the wide range of biological properties such as the anticancer, antibacterial, anti-inflammatory, antimalarial and antihypertensive activities. During the past decades, several patents and articles have been published in international peer-reviewed literature regarding the discovery and development of original and promising quinazoline derivatives for cancer treatment. Although quinazolines are well known to inhibit EGFR, there is also a large panel of other therapeutic protein targets. AREAS COVERED This review summarized the new patents and articles published about quinazoline derivatives as anticancer drugs since 2011. EXPERT OPINION Since 2011, a lot of quinazoline compounds have shown EGFR inhibition. Unlike the first-generation EGFR inhibitors, they inhibit both wild-type and mutated EGFR. In recent years, a number of studies on quinazoline synthesis have been reported and used by several medicinal chemistry groups for better and easier development of new derivatives. Therefore, several patents have been approved for the use of quinazoline compounds as inhibitors of other kinases, histone deacetylase, Nox and some metabolic pathways. Because of the large number of proteins targeted, some high structural diversity is observed in patented quinazoline compounds. Due to the vast applications of quinazoline derivatives, development of novel quinazoline compounds as anticancer drugs remains a promising field.

Abstract
Vasicine (VAS), a potential natural cholinesterase inhibitor, exhibited promising anticholinesterase activity in preclinical models and has been in development for treatment of Alzheimer’s disease. This study systematically investigated the in vitro and in vivo metabolism of VAS in rat using ultra performance liquid chromatography combined with electrospray ionization quadrupole time-of-flight mass spectrometry. A total of 72 metabolites were found based on a detailed analysis of their 1H- NMR and 13C NMR data. Six key metabolites were isolated from rat urine and elucidated as vasicinone, vasicinol, vasicinolone, 1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-yl hydrogen sulfate, 9-oxo-1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-yl hydrogen sulfate, and 1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-β-D-glucuronide. The metabolic pathway of VAS in vivo and in vitro mainly involved monohydroxylation, dihydroxylation, trihydroxylation, oxidation, desaturation, sulfation, and glucuronidation. The main metabolic soft spots in the chemical structure of VAS were the 3-hydroxyl group and the C-9 site. All 72 metabolites were found in the urine sample, and 15, 25, 45, 18, and 11 metabolites were identified from rat feces, plasma, bile, rat liver microsomes, and rat primary hepatocyte incubations, respectively. Results indicated that renal clearance was the major excretion pathway of VAS. The acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of VAS and its main metabolites were also evaluated. The results indicated that although most metabolites maintained potential inhibitory activity against AChE and BChE, but weaker than that of VAS. VAS undergoes metabolic inactivation process in vivo in respect to cholinesterase inhibitory activity.

Quinazoline based small molecule exerts potent tumour suppressive properties by inhibiting PI3K/Akt/FoxO3a signalling in experimental colon cancer. Cancer Lett 2014; 359:47-56. [PMID: 25554016 DOI: 10.1016/j.canlet.2014.12.034] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2014] [Revised: 12/11/2014] [Accepted: 12/12/2014] [Indexed: 01/22/2023]
Abstract
Deregulation of PI3K signalling pathway is strongly involved in pathology of cancer and development of resistance in tumour cells. Here, we report that pharmacologically active vasicinone analogue, RLX (7, 8, 9, 10-Tetrahydroazepino [2, 1-b] quinazolin-12-(6H)-on), exhibited potent anticancer activities both in vitro and in vivo. In this study, RLX treatment displayed strong inhibition of proliferation against various cancer cell lines. However, colon cancer cells were found to be the most sensitive towards RLX mediated inhibition of proliferation. The result showed that RLX treatment followed strong concentration dependent inhibition of HCT-116 cell proliferation and colony formation. RLX treatment to HCT-116 was observed to be associated with down-regulation of p110α and p85 subunits of PI3K thereby decreasing the expression of subsequent downstream effector proteins. Interestingly, silencing of PI3K gene by siRNA in combination with RLX confirmed the anti-proliferation effect of RLX against HCT-116 cells and is mediated by the PI3K pathway. We also found that RLX induced sub-G1 arrest and mitochondrial potential loss followed by pFoxO3a(Thr32) nuclear-cytoplasmic translocation inhibition. Moreover, RLX treatment in in vivo models substantially resulted in a tumour growth inhibition. Overall, our findings reveal the functional role of the PI3K/Akt/FoxO3a pathway that gets deregulated in cancer and suggests its simultaneous targeting by RLX thereby further identifying the compound as a potent inhibitor of the PI3K/Akt/FoxO3a pathway under in vitro and tumour regression in vivo.

Evaluation of anti-inflammatory and mechanism of action of extract of Macrosiphonia longiflora (Desf.) Müll. Arg. JOURNAL OF ETHNOPHARMACOLOGY 2014; 154:319-329. [PMID: 24681039 DOI: 10.1016/j.jep.2014.03.017] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2013] [Revised: 01/31/2014] [Accepted: 03/06/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Macrosiphonia longiflora (Desf.) Müll. Arg (Apocynaceae), popularly known as 'velame' and 'velame branco', is a native subshrub that grows in the Brazilian Cerrado. This plant is widely used in traditional medicine in the form of decoction and infusion, particularly as anti-inflammatory, depurative, anti-rheumatic, antisyphilitic and antiulcer remedy. There is no available information in the literature that has addressed its pharmacological activity and phytochemical analysis. AIM OF THE STUDY This study aimed to evaluate the anti-inflammatory pharmacological profile of the hydroethanolic extract of Macrosiphonia longiflora, using in vivo and in vitro acute inflammation experimental models, as well as investigate the roles of cytokines and nitric oxide in its mechanism of action, and including phytochemical analysis constitution of its hydroethanolic extract. MATERIALS AND METHODS Hydroethanolic (70%) extract of Macrosiphonia longiflora (HEMl) was prepared by maceration. The preliminary phytochemical analysis was performed according to procedures described in the literature. Selected secondary metabolites detected were quantified by spectrophotometry and high performance liquid chromatography (HPLC). Its cytotoxic potential in Chinese hamster ovary (CHO-k1) epithelial cell lines was evaluated using Alamar Blue. in vivo anti-inflammatory activity was evaluated with carrageenan- and dextran-induced paw edemas, carrageenan-induced pleurisy in rats and lipopolysaccharide (LPS)-induced peritonitis in mice. The in vitro anti-inflammatory activity was evaluated using RAW 264.7 cells stimulated with LPS and interferon (INF)-γ. Effects of HEMl on the inflammatory cytokines (IL-1β, IL-10, IL-17, INF-γ and TNF-α) concentrations in the peritoneal lavage were evaluated using commercial ELISA kits, while the Griess method was employed to determine nitric oxide (NO) concentrations in the peritoneal lavage, as well as in the supernatants of RAW 264.7 cells. RESULTS Preliminary phytochemical analysis, revealed the presence of phenolics compounds, terpenoids, alkaloids and flavonoids. Spectrophotometric analysis revealed the presence of relatively high content of phenolics and flavonoids in HEMl. HPLC analysis confirmed the presence of the quantified compounds and demonstrated the presence of ellagic acid in the detected matrix of compounds. HEMl appeared to be non-cytotoxic. It effectively inhibited (p<0.05) paw edema induced by carrageenan and dextran. Furthermore, HEMl also significantly reduced exudates volume and leukocyte migration in the carrageenan-induced pleurisy and LPS-induced peritonitis, neutrophils counts in LPS-induced peritonitis. HEMl also acts by effectively inhibiting the following inflammatory cytokines: IL-1β and IL-10 levels in the peritoneal lavage, but had no effect on IL-17 level in the peritonitis model. In addition, HEMl had no effect on the levels of tumor necrosis factor alpha (TNF-α) present in the peritoneal lavage and cells supernatants. The concentration of NO, as assessed by measurement of nitrite (NO2(-)), showed that pretreatment with HEMl reduced NO significantly in the peritoneal lavage and in RAW 264.7 cells co-stimulated with LPS and INF-γ. CONCLUSION The results obtained in this study indicate that HEMl possesses very low cytotoxic potential. In addition, it demonstrated a potent anti-inflammatory activity in both the in vivo and in vitro models of acute inflammation. The anti-inflammatory effect is partly related to the inhibition of IL-1β, IL-10, and nitric oxide releases, but independent of TNF-α and IL-17 modulation. Phytochemical analysis revealed the predominant presence of the flavonoids (naringin, rutin, myricetin, morin, quercetin, (±)-naringenin, and luteolin) and phenols (ellagic acid), which are possibly involved in the anti-inflammatory effect of HEMl. The current study provided supportive evidence for the popular use of HEMl in the treatment of inflammatory conditions, and shed more light on the possible roles of the inflammatory cytokines in its mechanisms of action as anti-inflammatory agent.
