Abstract
Acute lung injury (ALI) is one of the most common complications in COVID-19 and also a syndrome of acute respiratory failure with high mortality rates, but lacks effective therapeutic drugs. Natural products provide inspiration and have proven to be the most valuable source for bioactive molecule discovery. In this study, the chemical evolution of the natural product Tanshinone IIA (Tan-IIA) to achieve a piperidine-fused scaffold through a synthetic route of pre-activation, multi-component reaction, and post-modification is presented. Through biological evaluation, it is pinpointed that compound 8b is a standout candidate with remarkable anti-inflammation and anti-oxidative stress properties, coupled with low toxicity. The mechanistic study unveils a multifaceted biological profile of 8b and shows that 8b is highly efficient in vivo for the treatment of ALI. Therefore, this work not only provides an effective strategy for the treatment of ALI, but also offers a distinctive natural product-inspired drug discovery.

Abstract
Background Compounds possessing urea/thiourea moiety have a wide range of biological properties including anticancer activity. On the other hand, taking advantage of the low toxicity and structural diversity of hydrazone derivatives, they are presently being considered for designing chemical compounds with hydrazone moiety in the field of cancer treatment. With this in mind, a series of novel ureido/thioureido derivatives possessing a hydrazone moiety bearing nitro and chloro substituents (4a–4i) have been designed, synthesized, characterized and evaluated for their in vitro cytotoxic effect on HT-29 human colon carcinoma and HepG2 hepatocarcinoma cell lines. Results Two compounds (4c and 4e) having the chloro phenylurea group hybridized with phenyl hydrazone bearing nitro or chloro moieties demonstrated potent anticancer effect with the IC50 values between 2.2 and 4.8 µM at 72 h. The mechanism of action of compound 4c was revealed in hepatocellular carcinoma cells as an inducer of apoptosis in a caspase-independent pathway. Conclusion Taken together, the current work presented compound 4c as a potential lead compound in developing future hepatocellular carcinoma chemotherapy drugs. Methods The compounds were synthesized and then characterized by physical and spectral data (FT-IR, 1H-NMR, 13C-NMR, Mass). The anticancer activity was assessed using MTT assay, flowcytometry, annexin-V, DAPI staining and Western blot analysis. Graphical Abstract ![]()

Sulindac acetohydrazide derivative attenuates against cisplatin induced organ damage by modulation of antioxidant and inflammatory signaling pathways. Sci Rep 2022; 12:11749. [PMID: 35817806 PMCID: PMC9273647 DOI: 10.1038/s41598-022-15950-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 07/01/2022] [Indexed: 11/08/2022] Open
Abstract
This study aimed to explore the mechanisms of action of a sulindac acetohydrazide derivative, N'-(4-dimethylaminobenzylidene)-2-1-(4-(methylsulfinyl) benzylidene)-5-fluoro-2-methyl-1H-inden-3-yl) acetohydrazide, against anticancer drug cisplatin induced organ damage. Using a rodent model, various markers of organ function and signaling pathways were examined and validated by molecular docking studies. The study involves five groups of animals: control, DMSO, CDDP, CDDP + DMFM, and DMFM. Biochemical enzyme activity, histopathology, tissue antioxidant, and oxidative stress markers were examined. RT-PCR and western blot analyses were conducted for the expression of inducible cyclooxygenase enzyme (COX-2), nuclear factor kappa beta (NF-κB), p65, IL-1, TNF-α, and inducible nitric oxide synthase (iNOS). Flow cytometry analysis of CD4 + TNF-α, CD4 + COX-2, and CD4 + STAT-3 cells in whole blood was performed. Structural and dynamic behavior of DMFM upon binding with receptor molecule molecular docking and dynamic simulations were performed using bioinformatics tools and software. Treatment with DMFM reversed cisplatin-induced malondialdehyde (MDA) and nitric oxide (NO) induction, whereas the activity of glutathione peroxidase (GPx), and superoxide dismutase (SOD) in the kidney, heart, liver, and brain tissues were increased. DMFM administration normalized plasma levels of biochemical enzymes. We observed a marked decline in CD4 + STAT3, TNF-α, and COX2 cell populations in whole blood after treatment with DMFM. DMFM downregulated the expression factors related to inflammation at the mRNA and protein levels, i.e., IL-1, TNF-α, iNOS, NF-κB, STAT-3, and COX-2. Dynamic simulations and in silico docking data supports the experimental findings. Our experimental and in silico results illustrated that DMFM may affect protective action against cisplatin-induced brain, heart, liver, and kidney damage via reduction of inflammation and ROS.

Abstract
In the current study a late-stage diversification of unactivated olefins labd-8(17)-en-15-oic acid (1a) and methyl labd-8(17)-en-15-oate (1b) via Heck-Matsuda arylation is described. The reaction provided straightforward and practical access to a series of novel aryl-labdane-type derivatives (HM adducts 3a-h) in moderate to good yields in a highly regio- and stereoselective manner at room temperature under air atmosphere. The cytotoxic activity of these compounds was investigated in vitro against three different human cell lines (THP-1, K562, MCF-7). Of these, HM adduct 3h showed a selective effect in all cancer cell lines tested and was selected for extended biological investigations in a leukemia cell line (K562), which demonstrated that the cytotoxic/antiproliferative activity observed in this compound might be mediated by induction of cell cycle arrest at the sub-G1 phase and by autophagy-induced cell death. Taken together, these findings indicate that further investigation into the anticancer activity against chronic myeloid leukemia from aryl-labdane-type derivatives may be fruitful.

Abstract
Cisplatin is an efficient anticancer drug against various types of cancers however, its usage involves side effects. We investigated the mechanisms of action of indole derivative, 2-(5-methoxy-2-methyl-1H-indol-3-yl)-N'-[(E)-(3-nitrophenyl) methylidene] acetohydrazide (MMINA) against anticancer drug (cisplatin) induced organ damage using a rodent model. MMINA treatment reversed Cisplatin-induced NO and malondialdehyde (MDA) augmentation while boosted the activity of glutathione peroxidase (GPx), and superoxide dismutase (SOD). The animals were divided into five groups (n = 7). Group1: Control (Normal) group, Group 2: DMSO group, Group 3: cisplatin group, Group 4: cisplatin + MMINA group, Group 5: MMINA group. MMINA treatment normalized plasma levels of biochemical enzymes. We observed a significant decrease in CD4+COX-2, STAT3, and TNF-α cell population in whole blood after MMINA dosage. MMINA downregulated the expression of various signal transduction pathways regulating the genes involved in inflammation i.e. NF-κB, STAT-3, IL-1, COX-2, iNOS, and TNF-α. The protein expression of these regulatory factors was also downregulated in the liver, kidney, heart, and brain. In silico docking and dynamic simulations data were in agreement with the experimental findings. The physiochemical properties of MMINA predicted it as a good drug-like molecule and its mechanism of action is predictably through inhibition of ROS and inflammation.

Abstract
This study was aimed to design novel diclofenac hydrazones having anti-inflammatory and analgesic activity with gastric sparing effect. A new series of 2-[2-(2,6-dichloroanilino)phenyl]-N’-[(substituted phenyl) methylidene] acetohydrazide derivatives (1−14) were synthesized and evaluated for their anti-inflammatory, analgesic, and ulcerogenic activity. The compounds were identified and confirmed by elemental analysis and spectral data. During anti-inflammatory activity by carrageenan-induced paw edema method, compounds (2, 3, 7, 8, 11, and 13) were found to be most promising. Compounds 3, 8, and 13 have been found to have significant analgesic activity compared to the reference drug diclofenac in analgesic activity by both the hot plate method and acetic acid-induced writhing method. The compounds which presented highly significant anti-inflammatory and analgesic activity were further tested for their ulcerogenic activity. Compounds 3 and 8 showed maximum ulcerogenic reduction activities. Compound 8 was found to have LD50 of 168 mg/kg. Compound 8 with 3,5-dimethoxy-4-hydroxyphenyl substitution was found to be the most promising anti-inflammatory and analgesic agent with gastric sparing activity. Molecular docking of compounds was performed for COX−1/COX−2 binding site. Lead compound 8 showed better binding affinities of −9.4 kJ/mol with both COX-1 and COX-2 as compared to the standard drug, diclofenac with binding affinities of −6.6 kJ/mol and −8.1 kJ/mol for COX−1 and COX−2, respectively.

Abstract
Inducible nitric oxide synthase (iNOS), which is expressed in response to bacterial/proinflammatory stimuli, generates nitric oxide (NO) that provides cytoprotection. Overexpression of iNOS increases the levels of NO, and this increased NO level is implicated in pathophysiology of complex multifactorial diseases like Parkinson's disease, Alzheimer's disease, multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease. Selective inhibition of iNOS is an effective approach in treatment of such complex diseases. l-Arginine, being a substrate for iNOS, is the natural lead to develop iNOS inhibitors. More than 200 research reports on development of nitric oxide synthase inhibitors by different research groups across the globe have appeared in literature so far. The first review on iNOS, in 2002, discussed the iNOS inhibitors under two classes that is, amino acid and non-amino acid derivatives. Other review articles discussing specific chemical classes of iNOS inhibitors also appeared during last decade. In the present review, all reports on both natural and synthetic iNOS inhibitors, published 2002 onwards, are studied, classified, and discussed to provide comprehensive information on iNOS inhibitors. The synthetic inhibitors are broadly classified into two categories that is, arginine and non-arginine analogs. The latter are further classified into amidines, five- or six-membered heterocyclics, fused cyclics, steroidal type, and chalcones analogs. Structures of the most/significantly potent compounds from each report are provided to know the functional groups important for incurring iNOS inhibitory activity and selectivity. This review is aimed to provide a comprehensive view to the medicinal chemists for rational designing of novel and potent iNOS inhibitors.

Abstract
4-Hydroxy-2-(4-hydroxyphenethyl)isoindoline-1,3-dione (PD1) is a synthetic phthalimide derivative of a marine compound. PD1 has peroxisome proliferator-activated receptor (PPAR) γ agonistic and anti-inflammatory effects. This study aimed to investigate the effect of PD1 on allergic asthma using rat basophilic leukemia (RBL)-2H3 mast cells and an ovalbumin (OVA)-induced asthma mouse model. In vitro, PD1 suppressed β-hexosaminidase activity in RBL-2H3 cells. In the OVA-induced allergic asthma mouse model, increased inflammatory cells and elevated Th2 and Th1 cytokine levels were observed in bronchoalveolar lavage fluid (BALF) and lung tissue. PD1 administration decreased the numbers of inflammatory cells, especially eosinophils, and reduced the mRNA and protein levels of the Th2 cytokines including interleukin (IL)-4 and IL-13, in BALF and lung tissue. The severity of inflammation and mucin secretion in the lungs of PD1-treated mice was also less. These findings indicate that PD1 could be a potential compound for anti-allergic therapy.

Abstract
AbstractA new, selective and sensitive HPLC method for the determination of lixivaptan, an oral selective vasopressin 2 (V2)-receptor antagonist, was investigated and validated. A Waters symmetry C18 column was used as a stationary phase in isocratic elution mode using a mobile phase composed of KH2PO4(100 mM)-acetonitrile (40: 60, v/v) at a flow rate of 1.5 mL min-1. Diclofenac was used as the internal standard (IS). Lixivaptan and the IS were extracted from plasma by protein precipitation and were detected at 260 nm. Lixivaptan and diclofenac were eluted at 3.6 and 6.2 min, respectively. The developed method showed good linearity over the calibration range of 50 -1000 ng mL-1with a lower limit of detection of 16.5 ng mL-1. The extraction percentage of lixivaptan in the mouse plasma was in the range of 88.88 - 114.43%, which indicates acceptable extraction. The aforementioned method was validated according to guidelines of the International Council on Harmonization (ICH). The intra- and inter-day coefficients of variation did not exceed 5.5%. This method was presented to be simple, sensitive, and accurate and was successfully adapted in a pharmacokinetic study of the profile of lixivaptan in mouse plasma. A mean maximum plasma concentration of lixivaptan of 113.82 ng mL-1was achieved in 0.5 h after oral administration of a 10 mg kg-1dose in mouse as determined using the developed method.

Abstract
A new series of 2-(5-methoxy-2-methyl-1H-indol-3-yl)-N′-[(E)-(substituted phenyl) methylidene] acetohydrazide derivatives (S1–S18) were synthesized and evaluated for their anti-inflammatory activity, analgesic activity, ulcerogenic activity, lipid peroxidation, ulcer index and cyclooxygenase expression activities. All the synthesized compounds were in good agreement with spectral and elemental analysis. Three synthesized compounds (S3, S7 and S14) have shown significant anti-inflammatory activity as compared to the reference drug indomethacin. Compound S3 was further tested for ulcerogenic index and cyclooxygenase (COX) expression activity. It was selectively inhibiting COX-2 expression and providing the gastric sparing activity. Docking studies have revealed the potential of these compounds to bind with COX-2 enzyme. Compound S3 formed a hydrogen bond between OH of Tyr 355 and NH2 of Arg 120 with carbonyl group and this hydrogen bond was similar to that formed by indomethacin. This study provides insight for compound S3, as a new lead compound as anti-inflammatory agent and selective COX-2 inhibitor.

Abstract
Single-target inhibition is an unsatisfactory therapeutic option to treat multifactorial pathologies, brought into limelight 'paradox of inflammation' beside dearth of innovation, rationalizes a shift toward 'multiple-target' design concept in anti-inflammatory research field. To improvise, two platform strategies, drugs mixture or multitarget drugs, are plausible. Dual cyclooxygenase/lipoxygenase inhibitor 'licofelone' developed after the backfire of rofecoxib due to safety concerns has fetched first light of triumph of the latter strategy. As hitting multiple targets in restraint is perhaps more viable strategy rather than single target, this review, outlines the most germane multiple target agents of synthetic and natural origin placing clear advantage in favors of multitarget strategy as real therapeutic solution for inflammation.

Abstract
The lipophilic derivative of thalidomide (4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N′-[(4-ethoxyphenyl)methylidene]benzohydrazide, 6P) was synthesized to enhance its characteristics and efficacy. Earlier studies have proved the immunomodulatory and anti-inflammatory effects of 6P. In this study the interaction between bovine serum albumin (BSA) and 6P was studied using a multi-spectroscopic approach which included UV spectrophotometry, spectrofluorimetry and three dimensional spectrofluorometric and molecular docking studies. Static quenching was involved in quenching the fluorescence of BSA by 6P, because a complex formation occurred between the 6P and BSA. The binding constant decreased with higher temperature and was in the range of 2.5 × 105–4.8 × 103 L mol−1 suggesting an unstable complex at higher temperatures. A single binding site was observed and the the site probe experiments showed site II (sub-domain IIIA) of BSA as the binding site for 6P. The negative values of ∆G0, ∆H0 and ∆S0 at (298/303/308 K) indicated spontaneous binding between 6P and BSA as well as the interaction was enthalpy driven and van der Waals forces and hydrogen bonding were involved in the interaction. The docking results and the results from the experimental studies are complimentary to each other and confirm that 6P binds at site II (sub-domain IIIA) of BSA.

Abstract
The first general and efficient non-noble metal-catalysed reductive C2-alkoxylation of cyclic imides (phthalimides and succinimides) is presented. Crucial for the success is the use of [Co(BF4)2·6H2O/triphos (L1)] combination and no external additives are required.
The first general and efficient non-noble metal-catalysed reductive C2-alkoxylation of cyclic imides (phthalimides and succinimides) is presented. Crucial for the success is the use of [Co(BF4)2·6H2O/triphos (L1)] combination and no external additives are required. Using the optimal cobalt-system, the hydrogenation of the aromatic ring of the parent phthalimide is avoided and only one of the carbonyl groups is selectively functionalized. The resulting products, N- and aryl-ring substituted 3-alkoxy-2,3-dihydro-1H-isoindolin-1-one and N-substituted 3-alkoxy-pyrrolidin-2-one derivatives, are prepared under mild conditions in good to excellent isolated yields. Intramolecular reductive couplings can also be performed affording tricyclic compounds in a one-step process. The present protocol opens the way to the development of new base-metal processes for the straightforward synthesis of functionalized N-heterocyclic compounds of pharmaceutical and biological interest.

Abstract
A thalidomide analog, (4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N'-[(4-ethoxyphenyl) methylidene] benzohydrazide), has been identified as a promising broad-spectrum anti-inflammatory agent in previous study. In this study, a sensitive and selective UPLC-MS/MS assay was developed and validated for its determination in rat plasma samples. The chromatographic separation was performed on an Aquity BEH C18 column using mobile phase comprising of acetonitrile and 10 mm ammonium acetate in the ratio of 85: 15, at flow rate of 0.3 mL/min. The detection and quantification were performed in positive multiple reaction monitoring mode by parent to daughter ion transition of 414.06 ˃ 148.05 for analyte and 411.18 ˃ 191.07 for internal standard (risperidone), respectively using electrospray ionization source. The sample extraction process consisted of liquid-liquid extraction method using diethyl ether as the extracting solvent. The assay was validated by following FDA guidelines and all parameters were found to be within acceptable limits. The linearity was between 10.1 and 2500 ng/mL and the lower limit of quantification was 10.1 ng/mL. The reported results indicate that the assay could meet the requirement for analysis of this compound in amounts expected to the present in actual samples. Further, in vitro metabolic stability study was performed in rat liver microsomes by using the validated assay.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a chronic progressive interstitial lung disease with severe pulmonary fibrosis. The main cause of IPF-associated death is acute exacerbation of IPF (AE-IPF). This study aims to develop a rat model of AE-IPF by two intratracheal perfusions with bleomycin (BLM). METHODS Ninety male Sprague Dawley (SD) rats were randomized into three groups: an AE-IPF model group (BLM + BLM group), an IPF model group (BLM group), and a normal control group. Rats in the BLM + BLM group underwent a second perfusion with BLM on day 28 after the first perfusion with BLM. Rats in the other two groups received saline as the second perfusion. Six rats in each group were sacrificed on day 31, day 35, and day 42 after the first perfusion, respectively. Additional 18 rats in each group were observed for survival. RESULTS Rats in the BLM + BLM group had significantly worse pulmonary alveolar inflammation and fibrosis than rats in the BLM group. Rats in the BLM + BLM group also developed large amounts of hyaline membrane, showed high levels of albumin (ALB) and various inflammatory factors in the bronchoalveolar lavage fluid (BALF), and had markedly increased lung water content. Furthermore, rat survival was reduced in the BLM + BLM group. The pathophysiological characteristics of rats in the BLM + BLM group resemble those of patients with AE-IPF. CONCLUSIONS A second perfusion with BLM appears to induce acute exacerbation of pulmonary fibrosis and may be used to model AE-IPF in rats.
