Abstract
A series of 1,3,4-oxadiazole contained sesquiterpene derivatives were synthesized, and the activity of the target compounds against Xanthomonas oryzae pv. oryzae (Xoo), Xanthomonas axonopodis pv. citri (Xac), and tobacco mosaic virus (TMV) were evaluated. The biological activity results showed that the EC50 values of compounds H4, H8, H11, H12, H14, H16, and H19 for Xac inhibitory activity were 33.3, 42.7, 56.1, 74.5, 37.8, 43.8, and 38.4 μg/ml, respectively. Compounds H4, H8, H15, H19, H22, and H23 had inhibitory effects on Xoo, with EC50 values of 51.0, 43.3, 43.4, 50.5, 74.6, and 51.4 μg/ml, respectively. In particular, the curative and protective activities of compound H8 against Xoo in vivo were 51.9 and 49.3%, respectively. In addition, the EC50 values of the inactivation activity of compounds H4, H5, H9, H10, and H16 against TMV were 69.6, 58.9, 69.4, 43.9, and 60.5 μg/ml, respectively. The results of molecular docking indicated that compound H10 exhibited a strong affinity for TMV-coat protein, with a binding energy of −8.88 kcal/mol. It may inhibit the self-assembly and replication of TMV particles and have an anti-TMV effect, which supports its potential usefulness as an antiviral agent.

Abstract
The alarming increase in multi- and extensively drug-resistant (MDR and XDR) strains of Mycobacterium tuberculosis (MTB) has triggered the scientific community to search for novel, effective, and safer therapeutics. To this end, a series of 3,5-disubstituted-1,2,4-oxadiazole derivatives (3a-3i) were tested against H37Rv, MDR and XDR strains of MTB. Of which, compound 3a with para-trifluorophenyl substituted oxadiazole showed excellent activity against the susceptible H37Rv and MDR-MTB strain with a MIC values of 8 and 16 µg/ml, respectively.To understand the mechanism of action of these compounds (3a-3i) and identify their putative drug target, molecular docking and dynamics studies were employed against a panel of 20 mycobacterial enzymes reported to be essential for mycobacterial growth and survival. These computational studies revealed polyketide synthase (Pks13) enzyme as the putative target. Moreover, in silico ADMET predictions showed satisfactory properties for these compounds, collectively, making them, particularly compound 3a, promising leads worthy of further optimisation.

Abstract
BACKGROUND Cancer disease is making a serious concern globally. Global cancer occurrence is steadily increasing every year. There is always a persistent need to develop new anticancer drugs with reduced side effects or act synergistically with the existing chemotherapeutics. OBJECTIVE Benzoxazoles are fused bicyclic nitrogen and oxygen-containing heterocyclic compounds and are considered biologically privileged scaffolds. We designed a synthetic route to link the benzoxazoles with oxadiazoles resulting in a better pharmacophore for anticancer activity. METHODS A series of novel amide derivatives of benzoxazole linked 1,3,4-oxadiazoles (10a-j) were synthesized and characterized by 1H NMR, 13C NMR, and mass spectroscopic techniques. The biological properties of the compounds were screened in vitro against four different tumor cell lines. RESULTS The results suggest that the compound 10b having 3,4,5-trimethoxy substitution on the phenyl ring exhibited potent anticancer activity in three cell lines (A549 = 0.13 ± 0.014 µM, MCF-7 = 0.10 ± 0.013 µM and HT-29 = 0.22 ± 0.017 µM). Notably, among the synthesized derivatives, compounds 10b, 10c, 10f, 10g, and 10i exhibited potent anticancer activity than the control IC50 in the range of 0.11 ± 0.02 to 0.93 ± 0.034 µM. Molecular docking simulation results showed compounds were stabilized by hydrogen bond and π-π interactions with the protein. CONCLUSION The molecules showed comparable binding affinities with standard Combretastatin-A4. The present research work is preliminary and needs further studies to take the synthesized compounds to the next level in the cancer research field.

Abstract
A series of novel 1,3,4-oxadiazole derivatives with substituted phenyl ring were designed and synthesized with an objective of discovering newer anti-cancer agents targeting thymidine phosphorylase enzyme (TP). The 1,3,4-oxadiazole derivatives were synthesized by simple and convenient methods in the lab. Chemical structure of the all the synthesized compounds were characterized by IR, 1H NMR and mass spectral methods and evaluated for cytotoxicity by MTT method against two breast cancer cell lines (MCF-7 and MDA-MB-231). Further, results of TP assay identified that 1,3,4-oxadiazole molecules displayed anti-cancer activity partially by inhibition of phosphorylation of thymidine. The TP assay identified SB8 and SB9 as potential inhibitors with anti-cancer activity against both the cell lines. The molecular docking studies recognized the orientation and binding interaction of molecule at the active site amino acid residues of TP (PDB: 1UOU). Acute toxicity studies of compound SB8 at the dose of 5000 mg/kg has identified no signs of clinical toxicity was observed. The SARs study of synthesized derivatives revealed that the substitution of phenyl ring with electron withdrawing group at ortho position showed significant TP inhibitory activity compared to para substitution. The experimental data suggests that 1,3,4-oxadiazole with substituted phenyl can be taken as a lead for the design of efficient TP inhibitors and active compounds which can be taken up for further studies.

Abstract
Background:
Cancer is a fatal disease for mankind; continuous research is still going on
for the invention of potent anticancer drugs. In this view, 1, 3, 4-Oxadiazoles are privileged molecules
which attracted medicinal chemists towards their anticancer properties.
Methods:
A new series of benzo[d]imidazol-5-yl)-5-(substituted)-1,3,4-oxadiazole derivatives was
synthesized in an efficient ‘one-pot’ nitro reductive cyclization using sodium dithionite as a cyclizing
agent by a conventional method with good yield. All the structures of the synthesized molecules were
characterized by IR, 1H NMR, HRMS and Mass spectral analysis. Anticancer activity screening
against A375 melanoma cancer cell line and MDA-MB-231 breast cancer cell line along with antimicrobial
activity were carried out using agar well diffusion method.
Results:
Compounds 8a and 8j of the series emerged as potent anticancer agents against A375 melanoma
cancer cell line with IC50 47.06 µM and 36.76 µM, respectively. In silico studies also revealed
that compounds 8a and 8j showed highest interaction with 2OH4 protein of VEGFR-2 tyrosine kinase.
Substantial antibacterial and antifungal activities against the tested microorganism were observed
for compounds 8j and 8g.
Conclusion:
Potent anticancer property has been observed with 1,3,4-Oxadiazole linked tetrafluro
substituted benzene ring 8j indicating that future research on these type of molecules can be
continued to improve the anticancer activity.

Abstract
One problem area regarding animal models for affective disorders is unclear reproducibility, including external validity or generalizability. One way to evaluate external validity is with systematic reviews and meta-analyses. The current study presents a meta-analysis of the effects of prototypic antidepressants in the mouse forced swim test (FST). We identified studies that examined effects of antidepressants in the FST in mice and used standard protocol, male mice and acute drug administration. We calculated Effect sizes using Cohen's d, homogeneity using Q statistic and correlations using Pearson's correlation. Results indicate that all drugs reduce immobility in the FST. However, effect sizes for most drugs are heterogeneous and do not show a consistent dose/response relationship across variability factors. Reducing variability by examining only one strain or data from individual laboratories partially increases dose response relationship. These findings suggest that whereas the FST is a valid tool to qualitatively screen antidepressant effects its validity in the context of hierarchical comparison between doses or compounds might be relevant only to single experiments.

Abstract
1,2,4-Triazoles and 1,3,4-oxadiazoles are prevalent moieties in pharmaceutical agents, yet fused [1,2,4]-triazolo[3,4-b][1,3,4]oxadiazoles are surprisingly under-represented for both synthesis and biological application. We report a rapid, two-step synthesis of [1,2,4]-triazolo[3,4-b][1,3,4]oxadiazoles from commercial 4-amino-1,2,4-triazoles that is highlighted by a microwave accelerated intramolecular cyclization to generate the fused ring system. Our efforts to optimize reaction conditions and elucidate reaction mechanism are also described.

Abstract
We report synthesis and antimicrobial evaluation of 42 novel 4-nitropyrrole-based 1,3,4-oxadiazoles. The synthesized molecules were evaluated for anti-bacterial, anti-fungal and anti-tubercular activities. Promisingly, most of the compounds showed equal or more potency than standard ciprofloxacin against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Compound 5e exhibited highest anti-tubercular activity (0.46 μg/mL) close to that of standard Isoniazid (0.40 μg/mL). Equal antifungal activity (1.56 μg/mL) compared to standard Amphotericin-B was shown by most of the compounds. All the N-methylated compounds showed more potent to equal activity against MSSA (MIC 0.39-1.56 μg/mL) and MRSA (MIC 0.78-1.56 μg/mL). All compounds were tested for mammalian cell toxicity using VERO cell line and were found to be non-toxic.
