Summary: A new series of pyrimidine-5-carbonitrile derivatives carrying the 1,3-thiazole moiety have been designed and synthesized as novel anti-inflammatory EGFR inhibitors with cardiac and gastric safety profiles. These compounds showed potent and selective COX-2 inhibition, significant in-vivo anti-inflammatory effects, and superior gastric safety profiles compared to meloxicam. Additionally, they exhibited cardiovascular safety, anti-proliferative effects, and superior inhibitory activity against wild-type EGFR.

Summary: A new series of substituted aryl carboximidamide VIa-o was designed and synthesised, and their structures were confirmed using spectroscopy and elemental analysis. The antiproliferative effect of these compounds against four cancer cell lines was investigated, and VIc, VIg, VIj, VIk, VIm, and VIo showed the strongest activity. Molecular docking simulations revealed that VIc, VIk, and VIo exhibited high affinity and active site interactions with EGFR and VEGFR-2 enzymes, suggesting their potential as dual inhibitors. Compound VIk demonstrated the highest induced levels of apoptotic markers in A-549 cancer cells, indicating its pro-apoptotic effect. ADME studies showed that the active compounds had good safety and pharmacokinetic profiles.

Summary: The investigation focused on designing and synthesizing purine/pteridine-based derivatives as dual inhibitors of EGFR and BRAF(V600E) for targeted cancer treatment. The majority of the compounds displayed promising antiproliferative activity on cancer cell lines. Compounds 5a, 5e, and 7e of purine-based and pteridine-based scaffolds were identified as the most potent hits, exhibiting strong anti-proliferative and EGFR inhibitory activities. However, the results suggested that BRAF(V600E) may not be a viable target for this class of organic compounds. Molecular docking studies provided insight into possible binding modes at the active sites of EGFR and BRAF(V600E).
