Profiling of the kinase-binding capabilities of an aminopyrimidine analogue detected in a cellular screen of the St. Jude small-molecule collection led to the identification of a novel series of FMS-like tyrosine kinase 3 (FLT3) inhibitors. Structure-activity relationship studies led to the development of compounds exhibiting good potency against MV4-11 and MOLM13 acute myelogenous leukemia cells driven by FLT3, regardless of their FLT3 mutation status. In vitro pharmacological profiling demonstrated that compound shows characteristics suitable for further preclinical development.

Overcoming clinical resistance to osimertinib mediated by the tertiary C797S mutation remains an unmet medical need. To date, there are no effective drugs that have been approved for patients who harbor EGFR mutations. Herein, we applied a structure-based drug design strategy to discover a series of potent and selective diaminopyrimidine macrocycles as novel EGFR inhibitors.

Nontuberculous mycobacteria (NTM) are emerging human pathogens linked to severe pulmonary diseases. Current treatments involve the prolonged use of multiple drugs and are often ineffective. Bacterial dihydrofolate reductase (DHFR) is a key enzyme targeted by antibiotics in Gram-negative bacterial infections.

The potential of cyclin-dependent kinases (CDKs) as therapeutic targets in cancer treatment is well established. In this study, we present our investigation into a group of 2,4-diaminopyrimidine derivatives that potently inhibit CDK9 and are cytotoxic when tested in colorectal cancer cell lines. We designed and synthesized forty analogues by altering substitutions at C-2 and C-4 position of the pyrimidine system.

Developing selective CDK7 inhibitors has emerged as a promising approach for cancer treatment owing to the critical role of CDK7 in cancer progression. Starting from BTX-A51, a CK1α inhibitor that also targets CDK7 and CDK9, we designed and synthesized a series of 2,4-diaminopyrimidine derivatives as potent CDK7 inhibitors. The representative compound, , displayed significant enzymatic inhibitory activity and demonstrated a remarkable selectivity profile against a panel of kinases, including seven CDK subtypes.

The cell cycle includes two checkpoint arrests allowing to repair of damaged DNA. Many cancer cell lines exhibit weak G1 checkpoint mechanisms relying significantly more on the G2 checkpoint than do healthy cells. Inhibition of Myt1 kinase (PKMYT1), a forgotten member of the Wee family, cyclin-dependent kinase 1 (Cdk1) inhibitory kinase, target for G2 checkpoint abrogation, whose inhibition forces cells into premature unchecked mitosis resulting in cell death, is a promising concept for anticancer therapy.
