Pharmaceuticals (Basel) 2023; 16:ph16040517. [PMID: 37111274 PMCID: PMC10146081 DOI: 10.3390/ph16040517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/17/2023] [Accepted: 03/17/2023] [Indexed: 04/03/2023] Open
Abstract
By exploiting the ample biological potential of 1,3,4-oxadiazole/thiadiazole ring, 4-substitutedphenyl-1,3,4-oxadiazol/Thiadiazol-2-yl)-4-(4-substitutedphenyl) azetidin-2-one derivatives were prepared. Various substituted azetidin-2-one derivatives have been identified as immunostimulating and antimicrobial, as well as their antioxidant activity. 2-amino 1,3,4 oxadiazole/thiadiazole conjugates were synthesized by mixing semi/thio carbazides and sodium acetate with water and stirring well, followed by adding aldehydes in methanol at room temperature. Acetate (glacial) was used as the catalyst to produce Schiff’s bases (intermediates) by treating substituted aldehydes with 2-amino 1,3,4 oxadiazole/thiadiazole(s). Using the mixture of triethylamine (dropwise) and chloroacetylchloride with vigorous stirring, 4-substitutedphenyl-1,3,4-oxadiazol/Thiadiazol-2-yl)-4-(4-substitutedphenyl) azetidin-2-one derivatives were prepared. The newly synthesized conjugates were evaluated for their anticancer potential using MCF-7 cell lines. Amoxicillin and fluconazole were used as reference drugs to determine their antimicrobial activity. Synthesized derivatives were evaluated for their antioxidant properties using 2-diphenyl-1-picrylhydrazyl (DPPH). In vitro cytotoxicity screening (MTTS assay) revealed that derivatives AZ-5, 9, 10, 14 and 19 demonstrated high efficacy with the percentage of inhibition at different concentration ranges (0.1 μM, 0.5 μM, 1 μM, 2 μM) of 89% to 94% μM as compared to doxorubicin as standard drug. The antimicrobial study indicated that compounds AZ-10, 19, and AZ-20 were found to have significant antimicrobial potential with MIC ranges of 3.34 µM to 3.71 µM in comparison to reference drugs having 4.29 µM to 5.10 µM. Based on antioxidant screening, most of the synthetic derivatives showed greater stability and effectiveness than the standard drug. According to the antioxidant screening, compounds AZ-5 and AZ-15 (IC50 = 45.02 μg/mL and 42.88 μg/mL, respectively) showed the greatest potency, as compared to ascorbic acid (IC50 = 78.63 μg/mL). Structure-activity relationship (SAR) studies of synthesized novel derivatives revealed that para-substituted halogen and nitro derivatives have remarkable potential against MCF-7 cancer cell lines and different microbial strains. Current evidence indicates that the synthesized derivatives may be promising candidates for use in the prevention and treatment of these infections. These synthesized compounds require further mechanism-based research to understand how they interact with the cells.

Pharmaceuticals (Basel) 2023; 16:254.

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
The worldwide development of antimicrobial resistance forces scientists to search for new compounds to which microbes would be sensitive. Many new structures contain the 1,3,4-oxadiazole ring, which have shown various antimicrobial activity, e.g., antibacterial, antitubercular, antifungal, antiprotozoal and antiviral. In many publications, the activity of new compounds exceeds the activity of already known antibiotics and other antimicrobial agents, so their potential as new drugs is very promising. The review of active antimicrobial 1,3,4-oxadiazole derivatives is based on the literature from 2015 to 2021.

Abstract
With the increasing number of cases of latent and drug resistant tuberculosis, there is an urgent need to develop new, potent molecules capable of combating this deadly disease. Molecules containing oxadiazoles are one such class that could be considered to fulfil this need. Oxadiazole regioisomers have been explored in drug discovery programs for their ability to act as effective linkers and also as pharmacophoric features. Oxadiazoles can act as bioisosteric replacements for the hydrazide moiety which can be found in first line anti-TB drugs, and some have been also reported to interact with newer anti-TB targets. In this context, the present review describes the potential of oxadiazoles as antituberculosis agents.

Abstract
Tuberculosis is a disease of global importance for which novel drugs are urgently required. We developed a whole-cell phenotypic screen which can be used to identify inhibitors of Mycobacterium tuberculosis growth. We used recombinant strains of virulent M. tuberculosis which express far-red fluorescent reporters and used fluorescence to monitor growth in vitro. We optimized our high throughput assays using both 96-well and 384-well plates; both formats gave assays which met stringent reproducibility and robustness tests. We screened a compound set of 1105 chemically diverse compounds previously shown to be active against M. tuberculosis and identified primary hits which showed ≥ 90% growth inhibition. We ranked hits and identified three chemical classes of interest-the phenoxyalkylbenzamidazoles, the benzothiophene 1-1 dioxides, and the piperidinamines. These new compound classes may serve as starting points for the development of new series of inhibitors that prevent the growth of M. tuberculosis. This assay can be used for further screening, or could easily be adapted to other strains of M. tuberculosis.
