Abstract
BACKGROUND Two significant families of compounds i.e. 1,3,4-oxadiazole and benzimidazole, have undergone extensive investigation into their pharmacological characteristics and possible therapeutic applications. Both classes have shown their potential in a variety of applications, and because of their synergistic interactions, they may have an even better therapeutic impact when combined. OBJECTIVES To produce a specific molecule with potent therapeutic properties, it is now common methods to combine at least two pharmacophores. This facilitates interaction with several targets, enhances biological functions, or eliminates adverse effects associated with them. CONCLUSION The synthesis of benzimidazole-1,3,4-oxadiazole hybrid compounds has recently involved the use of several synthetic techniques, all of which are detailed in the literature along with the advantages and disadvantages. It has been noted that the structure-activity relationship relates their pharmacological actions to their molecular structure. In order to set the stage for future research, the study aims to provide researchers with an effective toolbox and an understanding of benzimidazole and 1,3,4-oxadiazole hybrid compounds.

Abstract
The world's health system is plagued by cancer and a worldwide effort is underway to find new drugs to treat cancer. There has been a significant improvement in understanding the pathogenesis of cancer, but it remains one of the leading causes of death. The imperative 1,3,4-oxadiazole scaffold possesses a wide variety of biological activities, particularly for cancer treatment. In the development of novel 1,3,4-oxadiazole-based drugs, structural modifications are important to ensure high cytotoxicity towards malignant cells. These structural modification strategies have shown promising results when combined with outstanding oxadiazole scaffolds, which selectively interact with nucleic acids, enzymes, and globular proteins. A variety of mechanisms, such as the inhibition of growth factors, enzymes, and kinases, contribute to their antiproliferative effects. The activity of different 1,3,4-oxadiazole conjugates were tested on the different cell lines of different types of cancer. It is demonstrated that 1,3,4-oxadiazole hybridization with other anticancer pharmacophores have different mechanisms of action by targeting various enzymes (thymidylate synthase, HDAC, topoisomerase II, telomerase, thymidine phosphorylase) and many of the proteins that contribute to cancer cell proliferation. The focus of this review is to highlight the anticancer potential, molecular docking, and SAR studies of 1,3,4-oxadiazole derivatives by inhibiting specific cancer biological targets, such as inhibiting telomerase activity, HDAC, thymidylate synthase, and the thymidine phosphorylase enzyme. The purpose of this review is to summarize recent developments and discoveries in the field of anticancer drugs using 1,3,4-oxadiazoles.

Abstract
A Schiff base, 5-(4-methylphenyl)-4-[(pyridin-2-ylmethylidene)amino]-4H-1,2,4-oxadiazole as a bidentate ligand has been synthesized by the reaction between the 4-amino-5-(4-methylphenyl)-4H-1,3,4-oxadiazole and aromatic aldehyde. The Schiff base reacted with CoCl3·6H2O and CrCl3·6H2O in ethanol to yield 1,3,4-oxadiazole complexes. The structures of synthesized ligand and their complexes have been established on the basis of their IR, Mass and 1H-NMR spectra. Electronic and geometric structures of both cobalt and chromium complexes were investigated by density functional theory (DFT) and quantum theory of atoms in molecules (QTAIM) calculations. DFT-based reactivity calculations estimated the studied system as strong electrophile and/or strong nucleophile in polar organic reactions. Moreover, most reactive sites were predicted theoretically based on the delocalized and localized indexes. The nature of Ligand-Metal chemical bonding is discussed in terms of the natural bond orbital (NBO) and QTAIM analysis. Accordingly, the metal ions such as cobalt and chromium are bidentate coordinated with the Schiff base by nitrogen atoms of imine function and pyridine, to form stable complexes. Furthermore, the chromium ions have an affinity superior to the cobalt ions towards Schiff base ligand. In addition, the results of the antibacterial activity in-vitro show that the metal complexation confers an increase in the antibacterial activity of the complexed ligand compared to the free ligand against both Gram-positive and Gram-negative bacteria with broad spectrum activity. In silico molecular docking studies of the ligands and their complexes were applied to describe the probable binding modes into the active site of Escherichia coli (E. coli) FabH and Salmonella typhimurium LT2 neuraminidase (STNA) receptors. The increase in biological activity could be attributed to the high stability of the complexes and strong affinities to bacterial enzyme receptors.Communicated by Ramaswamy H. Sarma.

Abstract
Abstract:
Among the large variety of nitrogen and oxygen-containing heterocycles, 1,3,4-oxadiazole, the scaffold, has attracted considerable attention owing to its ability to show an extensive range of pharmacological actions. According to literature investigations, prepared 1,3,4-oxadiazole and its derivative are pharmacologically significant and consist of a variety of activities, such as anticonvulsant, anticancer, antioxidant, anti-inflammatory, antibacterial, antidiabetic, etc. These heterocyclics are formed mainly by the cyclization reactions of various reactants under diverse reaction circumstances. Therefore, significant efforts of organic chemists have been directed towards the synthesis of new drug candidates containing 1,3,4-oxadiazole subunits connected to an established potential pharmacophore to improve the efficacy and potency. This article aims to highlight recent publications on the various synthesis techniques of 1,3,4-oxadiazole and related compounds over the previous ten years (2011–2021). The purpose of this review is to help researchers by summarizing several synthetic strategies for synthesizing oxadiazole.

Abstract
A series of oxadiazole (7a-l) and hydroxypyrazoline derivatives (8a-l) incorporating thiazole were synthesized and characterized by spectral analysis (1H-NMR, 13C-NMR, Mass, and FT-IR). The synthesized compounds were screened for their in vitro cytotoxicity against MDA-MB231 and HT-29 human cell lines. Conjugates 7d, 7e, 7f, 7i, 7l, 8a, 8b, 8i and 8l exhibited significant antiproliferative activity on both MDA-MB231 and HT-29 cell lines. Flow cytometric analysis reveals that, 7i arrests both cells lines at Go/G1 phase whereas 8i induced G0/G1 arrest only in the HT-29 cells. Furthermore, Computational interaction studies of 7i and 8i exhibited its capacity of being a plausible CDK2 and BCL-2 inhibitor respectively. In addition, DNA binding of the synthesized compounds and DNA docking of 7i and 8i demonstrated the ability to interact with DNA. Compounds 7i and 8i causes' remarkable growth inhibition of MDA-MB231 and HT-29 cells but compound 8i was considerably effective against HT-29 cells. Overall these compounds can be practiced for further drug development.

Abstract
OBJECTIVE To investigate the pharmacological basis of its uses of Phyla nodiflora (P. nodiflora) for the treatment of anomalies predominantly by smooth muscle containing tissues such as gastrointestinal/vascular/broncho spasm and cardiovascular modulation. METHODS The crude hydroalcoholic extract of P. nodiflora (Pn.Cr) and its fractions were evaluated on isolated rabbit jejunum, rat trachea, aorta and atrium. To access the contractile or relaxant effects of testing materials, the tissues were mounted in isolated organ bath and responses were recorded with transducers coupled with data acquisition system. BALB/c mice were challenged with castor oil for the assessment of in-vivo antidiarrheal activity. Normotensive rats were used for in-vivo hypotensive study. RESULTS Hydroalcoholic extract of Pn.Cr at variable concentrations inhibited the natural spontaneous rhythm and 80 mmol/L K+ mediated contractions in isolated segment of jejunum with EC50 values of 3.18 and 1.91 mg/mL respectively. Verapamil, a Ca2+ channel blocker, demonstrated akin pattern in jejunum and therefore possibly suggesting calcium blocking activity. On isolated rat tracheal tissue, Pn.Cr showed relaxation of high-K+ and carbachol mediated contractions (EC50 values: 1.24 and 2.42 mg/mL). Pn.Cr treatment relaxed the rat aortic ring in a cumulative doses with high-K+ and phenylephrine-induced contractions (EC50 values 0.25 and 0.92 mg/mL). Activity based fractionation of Pn.Cr showed that dichloromethane fraction was more potent for relaxing the tissues spasm compared to aqueous fraction. In-vivo experiments, significant protection by Pn.Cr (P < 0.05) was observed in castor oil-induced diarrhea (50-500 mg/kg) whereas hypotensive effect in anesthetized rats was seen at the dose range of 1-10 mg/kg of Pn.Cr (P < 0.05). CONCLUSION This study suggests the blockage of calcium channel in the smooth muscles as a pharmacological application to make usage of P. nodiflora in the management of diarrhea, asthma and hypotensive effect.

Abstract
BACKGROUND AND OBJECTIVES Tuberculosis (TB) is one of the deadliest infectious diseases and comprises a global public health concern because co-infection with Human immunodeficiency virus (HIV) and, in particular, the continuous isolation of new Multidrug-resistant strains (MDR), rendering the discovery of novel anti-TB agents a strategic priority. One of the most effective first-line mycobactericidal drugs is Isoniazid (INH). Previously, we reported in vitro anti-mycobacterial activity against sensitive and MDR Mycobacterium tuberculosis strains of a new oxadiazole obtained from the hybridization of INH and palmitic acid. The present study evaluated the therapeutic potential of liposomes including Phosphatidylcholine (PC) and L-α Phosphatidic acid (PA) or PC and Cholesterol (Chol) containing 4-(5-pentadecyl-1,3,4-oxadiazol-2-yl)pyridine in BALB/c male mice infected by intratracheal (i.t.) route with drug-sensitive or MDR M. tuberculosis. METHODS The lipophilic 4-(5-pentadecyl-1,3,4-oxadiazol-2-yl)pyridine was obtained to mix INH and palmitoyl chloride. The in vivo anti-TB effect of this oxadiazole derivative contained in two different liposomes was tested in BALB/c mice infected with a sensitive strain of M. tuberculosis, initiating treatment 2 months post-infection, by i.t. route, of 50 μg of oxadiazole derivative for 1 month. In a second stage, mice were infected with an MDR (resistant to first-line drugs) and treated with 150 μg of an oxadiazole derivative carried by PC + Chol liposomes for 2 months. The effect of the oxadiazole derivative in vivo was determined by the quantification of lung bacilli loads and histopathology. RESULTS In comparison with control animals, drug-sensitive, strain-infected mice treated for 1 month with 50 μg of this oxadiazole derivative contained in the liposomes of PC + Chol showed a significant, 80% decrease of live bacilli in lungs, which correlated with the morphometric observation, and the group of MDR clinical isolate-infected mice treated with 150 μg of the oxadiazole derivative contained in the same type of liposome showed significantly lower lung bacillary loads than control mice, producing 90% of bacilli burden reduction after 2 months of treatment. CONCLUSION These results confirm and extend the reported highly efficient anti-mycobacterial activity of this lipophilic oxidazole derivative when it is carried by liposomes in mice suffering from late progressive pulmonary TB induced by drug-sensitive, and most prominently by, MDR strains.

[PMID: 25298582 PMCID: PMC4175889 DOI: 10.4103/0253-7613.140584] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2014] [Revised: 04/28/2014] [Accepted: 07/27/2014] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVE 1,3,4-oxadiazole ring is a versatile moiety with a wide range of pharmacological properties. The present work deals with the synthesis and evaluation of the anti-inflammatory activity of two novel 2,5-disubstituted-1,3,4-oxadiazoles (OSD and OPD). MATERIALS AND METHODS Carrageenan-induced rat hind paw edema was employed as an acute model of inflammation. For evaluating sub-acute anti-inflammatory activity, carrageenan-induced inflammation in rat air pouch was employed. Complete Freund's adjuvant-induced arthritis in rats was used as a model of chronic inflammation. To evaluate in vitro anti-inflammatory activity, lipopolysaccharide (LPS)-stimulated RAW264.7 cells were used. RESULTS OSD (100 mg/kg) reduced carrageen-induced paw edema by 60%, and OPD (100 mg/kg) produced a modest 32.5% reduction. OSD also reduced leukocyte influx and myeloperoxidase in carrageenan-induced rat air pouch model. In complete Freund's adjuvant-induced arthritis model, both OSD and OPD (200 mg/kg for 14 days) reduced paw edema and NO levels. In LPS-stimulated RAW264.7 cells, OSD and OPD inhibited formation of nitric oxide and reactive oxygen species, with OPD showing a better activity in comparison to OSD. CONCLUSIONS OSD was the better of the two compounds in in vivo models of inflammation. The o-phenol substitution at position 2 of oxadiazole ring in OSD may be responsible for its better in vivo anti-inflammatory activity. The ability of the compounds to inhibit LPS-induced pro-inflammatory mediator release suggests an anti-inflammatory mechanism targeting LPS-TLR4-NF-κB signalling pathway, which needs to be explored in detail. The disparate efficacy in vitro and in vivo also requires in-depth evaluation of the pharmacokinetics of these novel oxadiazoles.

Abstract
INTRODUCTION The oxadiazoles represent a class of five-membered heterocyclic compounds which are of considerable interest in different areas of medicinal chemistry and drug discovery. Oxadiazoles can exist in different regioisomeric forms and employ in various agents with a broad range of biological activities. This review covers the work reported on various biological activities of oxadiazole derivatives from 2010 to 2012. AREAS COVERED Oxadiazole derivatives attract great attention due to their different kinds of pharmaceutical activities including antiviral, antimicrobial, anticancer, anticonvulsant, antidiabetic and anti-inflammatory activity. This paper provides a general review of oxadiazole derivatives published in international journals and patented between 2010 and 2012. EXPERT OPINION Oxadiazoles have been used frequently in drug-like molecules as bioisosteres for ester and amide functionalities and displayed numerous prominent pharmacological effects. The broad pharmacological profile of oxadiazole derivatives has attracted the attention of many researchers to explore this scaffold to its multiple potential against several activities. Therefore, oxadiazole motif is likely to be present in other therapeutic molecules in the future.

Abstract
Five new 1-(2-(5-nitrofuran-2-yl)-5-(aryl)-1,3,4-oxadiazol-3-(2H)-yl) ethanone compounds 5a-e were synthesized by cyclization of N-acylhydrazones 4a-e with acetic anhydride under reflux conditions. Their structures were fully characterized by IR, ¹H-NMR, and ¹³C-NMR. Furthermore, evaluations of the antibacterial activity of the 1,3,4-oxadiazoles 5a-e and N-acylhydrazones 4a-e showed strong activity against several strains of Staphylococcus aureus, with MICs between 4 μg/mL to 32 μg/mL. In silico studies of the parameters of Lipinski's Rule of Five, as well as the topological polar surface area (TPSA), absorption percentage (% ABS), drug likeness and drug score indicate that these compounds, especially 4a and 5d, have potential to be new drug candidates.

Vasorelaxant and antihypertensive effect of Cocos nucifera Linn. endocarp on isolated rat thoracic aorta and DOCA salt-induced hypertensive rats. JOURNAL OF ETHNOPHARMACOLOGY 2011; 134:50-54.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fruits of Cocos nucifera Linn. (Arecaceae) have long been used in traditional medicine for the treatment of cardio-metabolic disorders. AIM OF THE STUDY To evaluate the ethanolic extract of Cocos nucifera Linn. endocarp (CNE) for its vasorelaxant activity on isolated rat aortic rings and antihypertensive effects in deoxycorticosterone acetate (DOCA) salt-induced hypertensive rats. MATERIALS AND METHODS Cocos nucifera Linn. endocarp was extracted with ethanol and characterized by HPLC. CNE was examined for its in vitro vascular relaxant effects in isolated norepinephrine, phenylephrine or potassium chloride pre-contracted aortic rings (both intact endothelium and denuded). In vivo anti-hypertensive studies were conducted in DOCA salt-induced uninephrectomized male Wistar rats. RESULTS Removal of endothelium or pretreatment of aortic rings (intact endothelium) with l-NNA (10μM) or ODQ (10 μM) followed by addition of contractile agonists prior to CNE significantly blocked the CNE-induced relaxation. Indomethacin (10μM) and atropine (1 μM) partially blocked the relaxation, whereas glibenclamide (10 μM) did not alter it. CNE significantly reduced the mean systolic blood pressure in DOCA salt-induced hypertensive rats (from 185.3 ± 4.7 mmHg to 145.6±6.1 mmHg). The activities observed were supported by the polyphenols, viz. chlorogenic acid, vanillic acid and ferulic acid identified in the extract. CONCLUSIONS These findings reveal that the vasorelaxant and antihypertensive effects of CNE, through nitric oxide production in a concentration and endothelium-dependent manner, is due to direct activation of nitric oxide/guanylate cyclase pathway, stimulation of muscarinic receptors and/or via cyclooxygenase pathway.

A possible correlation between the correction of endothelial dysfunction and normalization of high blood pressure levels by 1,3,4-oxadiazole derivative, an L-type Ca2+ channel blocker in deoxycorticosterone acetate and N(G)-nitro-l-arginine hypertensive rats. Chem Biol Interact 2009; 183:327-31. [PMID: 19912999 DOI: 10.1016/j.cbi.2009.11.001] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2009] [Revised: 10/29/2009] [Accepted: 11/02/2009] [Indexed: 11/20/2022]
Abstract
We have previously demonstrated the vasorelaxant activity of 1,3,4-oxadiazole derivative (NOX-1) through L-type Ca2+ channel blockage. In the present study, we investigated whether the correction of endothelial dysfunction is dependent on the normalization of high blood pressure levels by 1,3,4-oxadiazole derivative (NOX-1) in deoxycorticosterone acetate (DOCA-salt) and N(G)-nitro-l-arginine (L-NNA) hypertensive rats. In DOCA-salt and L-NNA hypertensive rats, the mean systolic blood pressure (MSBB) was 185.3+/-4.7 and 170.2+/-4.1 mmHg, whereas after administration of NOX-1 to hypertensive rats, MSBB was 127.8+/-4.5 and 120.2+/-5.1 mmHg, respectively. To study the endothelial dysfunction, concentration-response curves of norepinephrine (NE) and acetylcholine (Ach) were constructed in rat aortic rings isolated from normotensive, hypertensive (DOCA and L-NNA) and NOX-1 treated rats. NE-induced contractions and Ach-induced relaxations were significantly (p<0.05) decreased and increased, respectively in the aorta of NOX-1 treated rats. Vasorelaxant activity of NOX-1 was not abolished by pretreatment of aortic rings with L-NNA, 1H-[1,2,4] oxadiazolo [4,3-A] quinoxalin-1-one (ODQ), indomethacin or glibenclamide. The results suggest that the endothelial dysfunction can be corrected by the L-type Ca2+ channel blocker with endothelium-independent action and that is dependent on the normalization of high blood pressure levels. The antihypertensive and vasorelaxant effects of NOX-1 are mainly endothelial-independent and it can be used to treat hypertension, a state associated with endothelial dysfunction.
