RSC Med Chem 2024; 15:1626-1639.

Abstract
The epidermal growth factor receptor (EGFR) enzyme plays a critical role in governing the cell cycle, positioning it as a promising target for the development of anticancer drugs. In this study, we endeavored to design and synthesize innovative EGFR inhibitors with potential applications in anticancer therapy. A novel series of compounds, namely 3-(4-(4-(1,3,4-oxadiazol-2-yl)-1H-imidazol-2-yl)phenyl)-1,2,4-oxadiazoles (30a-j), were meticulously designed using FBDD efforts and synthesized. The synthesized compounds underwent thorough characterization using 1HNMR, 13CNMR, HRMS, and mass spectrum analyses. The in vitro anticancer activities of the newly developed compounds (30a-j) were evaluated against four human cancer cell lines such as prostate cancer (PC3 & DU-145), lung cancer (A549), and liver cancer (HEPG2) using the MTT method. The results, expressed as IC50 values, demonstrated significant anticancer activity for several compounds, with five compounds (30a, 30b, 30c, 30i, and 30j) exhibiting superior potency compared to the established anticancer drug etoposide. Notably, compound 30a emerged as the most promising compound, displaying potent cytotoxicity. We also conducted a screening of the compounds on the normal Vero cell line, revealing a pronounced selectivity of the compounds against cancer cell lines, with no observable impact on the normal cell lines. Moreover, the synthesized compounds were investigated for their impact on enzyme EGFR activity. The findings revealed a robust inhibitory effect against the EGFR wild-type enzyme and a 10-fold inferior potency against the mutant form of EGFR. This observation underscores the potential of the new derivatives as effective EGFRWT inhibitors with substantial anticancer efficacy. Further studies, including cell cycle analysis and apoptosis assays in HEPG2 cell lines, revealed cell cycle arrest at G1/G0 and G2 phases. We also evaluated the potential influence of compound 30a on the EGFR pathway using western blot analysis, revealing a significant inhibition of EGFR autophosphorylation in HEPG2 cells. In conclusion, our findings highlight the promise of these novel compounds as potent EGFR inhibitors, encouraging further investigation and development for the creation of novel and effective anticancer therapeutics.

Abstract
Pyrrole is one of the most widely used heterocycles in the pharmaceutical industry. Due to the importance of pyrrole structure in drug design and development, herein, we tried to conduct an extensive review of the bioactive pyrrole based compounds reported recently. The bioactivity of pyrrole derivatives varies, so in the review, we categorized them based on their direct pharmacologic targets. Therefore, readers are able to find the variety of biologic targets for pyrrole containing compounds easily. This review explains around seventy different biologic targets for pyrrole based derivatives, so, it is helpful for medicinal chemists in design and development novel bioactive compounds for different diseases. This review presents an extensive meaningful structure activity relationship for each reported structure as much as possible. The review focuses on papers published between 2018 and 2020.

Abstract
A new series of 2,4-disubstituted benzo[g]quinoxaline molecules have been synthesized, using naphthalene-2,3-diamine and 1,4-dibromonaphthalene-2,3-diamine as the key starting materials. The structures of the new compounds were confirmed by spectral data along with elemental microanalyses. The cytotoxic activity of all synthesized benzo[g]quinoxaline derivatives was assessed in vitro against the breast MCF-7 cancer cell line. The tested molecules revealed good cytotoxicity toward the breast MCF-7 cancer cell line, especially compound 3. The results of topoisomerase IIβ inhibition assay revealed that compound 3 exhibits potent inhibitory activity in submicromolar concentration. Additionally, compound 3 was found to cause pre-G1 apoptosis, and slightly increase the cell population at G1 and S phases of the cell cycle profile in MCF-7 cells. Finally, compound 3 induces apoptosis via Bax activation and downregulation of Bcl2, as revealed by ELISA assay.

Abstract
Thirty novel 2,5-disubstituted-1,3,4-oxadiazole derivatives bearing urea moiety were designed and synthesized. IR, 1H-NMR, 13C-NMR and mass spectroscopic methods and elemental analysis were used to confirm the structures of the compounds. Their monoamine oxidase inhibitory activity was determined against the MAO-A and MAO-B isoforms. None of the compounds showed the potent MAO-A inhibitory activity, while the MAO-B inhibition was significantly found in the range of 62 to 98%. Among them, the compounds H8, H9 and H12 bearing chloro substituent at the fourth position of phenylurea were found to show potent monoamine oxidase B inhibitory activity with IC50 values 0.039-0.066 µM. To define and evaluate the interaction mechanism between compound H8 and monoamine oxidase B, molecular docking studies have been made.

Abstract
α-aminophosphonate oxadiazoles (5a-m) were prepared in high yields by reacting of 1,3,4-oxadiazole acetohydrazide (3) with appropriate aldehydes and diethyl phosphite under Kabachnik-Fields conditions using Iron triflate as a catalyst. The reaction conditions were optimized using D-optimal experimental design. Possible reaction mechanisms were considered, and structures of the new products were based upon compatible elementary and spectroscopic evidence. In vitro antitumor activities of these compounds were evaluated against human cancer cell lines of colon (HCT116), breast (MCF7) and liver (HepG2) and compared with anticancer drug, Doxorubicin, employing standard MTT assay. Compounds 5i and 5l demonstrated good antiproliferative activities against HCT116 tumor cells comparable to doxorubicin with low cytotoxicity towards normal fetal colon cell (FHC). Additionally, their capacity to activate apoptosis cascade was studied in HCT116 cell line by investigating the activation of proteolytic caspases cascade, the levels of Cytochrome C, Bax and Bcl-2. Active caspase-3 level was enhanced by 6-8-folds in HCT116 cell line when stimulated with compounds 5i and 5l compared to the control. The level of Caspases 8 & 9 was also increased signifying that intrinsic and extrinsic pathways are both activated. They also induced Bax and down regulated Bcl-2 protein level in addition to over-expressing Cytochrome C level in HCT116 cell line. Also, HCT116 cell cycle was mainly arrested at the Pre-G1 and G2/M phases when treated with compounds 5i and 5l.
