P300 and CREB-binding protein (CBP) are ubiquitously expressed pleiotropic lysine acetyltransferases and play a key role as transcriptional co-activators that are essential for a multitude of cellular processes. Despite great importance, there is a lack of highly selective, potent, druglike p300/CBP inhibitors. Through the artificial-intelligence-assisted drug discovery pipeline and further optimization, we reported the discovery of novel, highly selective, potent small-mol. inhibitors of p300/CBP histone acetyltransferases (HAT) with desired druglike properties, exemplified by B026. Our data demonstrated that B026, with half maximal inhibitory concentration (IC₅₀) values of 1.8 nM to p300 and 9.5 nM to CBP enzyme inhibitory activity, is the most potent, selective p300/CBP HAT inhibitor. Moreover, B026 achieves significant and dose-dependent tumor growth inhibition in an animal model of human cancer, suggesting that B026 is a highly promising p300/CBP HAT inhibitor and warrants extensive preclin. investigation as a potential clin. development candidate.

These screening cascades revealed that I was a preferred compound with IC₅₀ values of 0.7 and 4 nM for JAK2 and FLT3, resp. Moreover, I was a potent JAK2 inhibitor with 37-fold and 56-fold selectivity over JAK1 and JAK3, resp., and possessed an excellent selectivity profile over the other 100 representative kinases. In a series of cytokine-stimulated cell-based assays, I exhibited a higher JAK2 selectivity over other JAK isoforms. The oral administration of 60 mg/kg of I could significantly inhibit tumor growth, with a tumor growth inhibition rate of 93 and 85% in MV4-11 and SET-2 xenograft models, resp. Addnl., I showed an excellent bioavailability (F = 58%), a suitable half-life time (T_1/2 = 4.1 h), a satisfactory metabolic stability, and a weak CYP3A4 inhibitory activity, suggesting that I might be a potential drug candidate for JAK2-driven myeloproliferative neoplasms and FLT3-internal tandem duplication-driven acute myelogenous leukemia.

Tropomyosin receptor kinase (TRK) represents an attractive oncol. target for cancer therapy related to its critical role in cancer formation and progression. NTRK fusions are found to occur in 3.3% of lung cancers, 2.2% of colorectal cancers, 16.7% of thyroid cancers, 2.5% of glioblastomas, and 7.1% of pediatric gliomas.

Transition metal catalyzed C-H phosphorylation remains an unsolved challenge. Reported methods are generally limited in scope and require stoichiometric silver salts as oxidants. Reported here is an electrochem. driven Rh^III-catalyzed aryl C-H phosphorylation reaction that proceeds through H₂ evolution, obviating the need for stoichiometric metal oxidants. The method is compatible with a variety of aryl C-H and P-H coupling partners and particularly useful for synthesizing triarylphosphine oxides from diarylphosphine oxides, which are often difficult coupling partners for transition metal catalyzed C-H phosphorylation reactions.

Although lung adenocarcinoma patients have benefited from the development of targeted therapy, patients with lung squamous cell carcinoma (SqCC) have no effective treatment due to the complexity and heterogeneity of the disease. Therefore, basing on the genetic anal. of mutations in lung squamous cell carcinoma to design multi-target inhibitors represents a potential strategy for the medical treatment. In this study, through screening an inhouse focused library, we identified an interesting indazole scaffold. And following with binding anal., we elaborated the structure-activity relationship of this hit compound by optimizing four parts guided by the DDR2 enzymic assay, which resulted in a potent lead compound 10a. We conducted further optimization of dual enzymic inhibitions towards FGFR1 and DDR2, two important kinases in lung squamous cell carcinoma. Finally, from the cellular antiproliferative activity tests and in vivo pharmacokinetic test, 3-substituted indazole derivative 11k was found to be a promising candidate and subjected to in vivo pharmacol. study with the mouse xenograft models, demonstrating profound anti-tumor efficacy. Addnl. in vitro druglike assessment reinforced that compound 11k could be valuable for SqCC drug development.
