A series of four bicyclic cores were prepared and evaluated as cyclin-dependent kinase-2 (CDK2) inhibitors. From the in-vitro and cell-based analysis, the pyrazolo[1,5-a]pyrimidine core (represented by 9) emerged as the superior core for further elaboration in the identification of novel CDK2 inhibitors.

Cancer remains a leading cause of morbidity and mortality worldwide, highlighting the urgent need for novel therapeutic agents. This study investigated the synthesis and biological evaluation of -alkyl ()-chalcone derivatives (-) as potential anticancer agents. The compounds were synthesized via aldol condensation of substituted aldehydes and acetophenones, with structures confirmed by IR, NMR, and mass spectrometry.

To better understand drug resistance mechanisms to CDK4/6 inhibitors and inform precision medicine, we analyze real-world multi-omics data from 400 HR+/HER2- metastatic breast cancer patients treated with CDK4/6 inhibitors plus endocrine therapies, including 200 pre-treatment and 227 post-progression samples. The prevalences of ESR1 and RB1 alterations significantly increase in post-progression samples. Integrative clustering analysis identifies three subgroups harboring different resistance mechanisms: ER driven, ER co-driven and ER independent.

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.

The mitogen-activated protein kinase (MAPK) pathway integrates growth factor signaling through extracellular signal-regulated kinase (ERK) to control cell proliferation. To study ERK dynamics, many researchers use an ERK activity kinase translocation reporter (KTR). Our study reveals that this ERK KTR also partially senses cyclin-dependent kinase 2 (CDK2) activity, making it appear as if ERK activity rises as cells progress through the cell cycle.

Cyclin dependent kinase 2 (CDK2) is responsible for enforcing progression through the G1-S phase transition. Mutations and alterations in the CDK2 signaling pathway are associated with various cancers, most commonly breast, ovarian, prostate, leukemia, and lymphoma. CDK2 inhibitors have shown promising preclinical and early clinical results, and this class of agents may be most effective against cancers with cyclin E overactivity.
