Substitution of the cyano-NNO-azoxy moiety (NC-N=(O)N-) for the nitroso group in NU6027, a potent and selective CDK2 inhibitor, affords a compound with slightly improved potency and comparable selectivity profile. A molecular modelling study indicates for this new scaffold a binding mode similar to the one adopted by other purine and pyrimidine analogues, and suggests a relevant role for a conserved water molecule in stabilizing the bioactive pose of this and other pyrimidine ligands. The introduction of aminosulfonylphenyl substituents on the 2-amino group of the pyrimidine increased the CDK2 inhibitory potency by two orders of magnitude, while maintaining the same degree of selectivity.

In this current work, we dedicated efforts to designing and synthesizing new 1,2,3-triazole-analogues (5a-d), (6a-d), and (7a-c) to act as dual VEGFR-2 and telomerase inhibitors with promising apoptotic potential. The synthesized analogues were examined against eleven diverse types of cancer cells and two normal cells to assess their ability to inhibit cell growth (GI%). Obviously, compound 7b showed the best average GI% (75.

Many cancers have displayed resistance to chemotherapeutic drugs over the past few decades. EGFR has emerged as a leading target for cancer therapy inhibiting tumor angiogenesis. Besides, studies strongly suggest that blocking telomerase activity could be an effective way to control the growth of certain cancer cells.

Background: The increasing prevalence of drug resistance in cancer therapy underscores the urgent need for novel therapeutic approaches. Dual enzyme inhibitors, targeting critical kinases such as CDK2 and TRKA, represent a promising strategy. The goal of this investigation was to design, synthesize, and evaluate a set of pyrazolo[1,5-]pyrimidine derivatives for their dual inhibition potential toward CDK2 and TRKA kinases, along with their potential antiproliferative against cancer cell lines.

Background: Cucurbitacin E glucoside (CEG), a prominent constituent of Cucurbitaceae plants, exhibits notable effects on cancer cell behavior, including inhibition of invasion and migration, achieved through mechanisms such as apoptosis induction, autophagy, cell cycle arrest, and disruption of the actin cytoskeleton.
Objective: Melanoma, the fastest-growing malignancy among young individuals in the United States and the predominant cancer among young adults aged 25 to 29, poses a significant health threat. This study aims to elucidate the apoptotic mechanism of CEG against the melanoma cancer cell line (A375).
