- Discovery of N-(4-(3-isopropyl-2-methyl-2 H-indazol-5-yl)pyrimidin-2-yl)-4-(4-methylpiperazin-1-yl)quinazolin-7-amine as a Novel, Potent, and Oral Cyclin-Dependent Kinase Inhibitor against Haematological Malignancies
-
Hematologic malignancies (HM) start in blood forming tissue or in the cells of the immune system. Cyclin-dependent kinases (CDKs) regulate cell cycle progression, and some of them control cellular transcription. CDK inhibition can trigger apoptosis and could be particularly useful in hematological malignancies. Herein, we describe our efforts toward the discovery of a novel series of quinazoline derivatives as CDK inhibitors. Intensive structural modifications lead to the identification of compound 37d as the most active inhibitors of CDKs 1, 2, 4, 8 and 9 with balancing potency and selectivity against CDKs. Further biological studies revealed that compound 37d can arrest the cell cycle and induce apoptosis via activating PARP and caspase 3. More importantly, compound 37d showed good antitumor efficacy in multiple HM mice xenograft models with no obvious toxicity. These results indicated that CDK 1, 2, 4, 8, and 9 inhibitors could be potentially used to treat certain hematologic malignancies.

-
Alkylation of 4-methoxy-1H-pyrazolo[3,4-d]pyrimidine (1b) with iodomethane in THF using NaHMDS as base selectively provided N2-methyl product 4-methoxy-2-methyl-2H-pyrazolo[3,4-d]pyrimidine (3b) in an 8/1 ratio over N1-methyl product (2b). Interestingly, conducting the reaction in DMSO reversed selectivity to provide a 4/1 ratio of N1/N2 methylated products. Crystal structures of product 3b with N1 and N7 coordinated to sodium indicated a potential role for the latter reinforcing the N2-selectivity. Limits of selectivity were tested with 26 heterocycles which revealed that N7 was a controlling element directing alkylations to favor N2 for pyrazolo- and N3 for imidazo- and triazolo-fused ring heterocycles when conducted in THF. Use of 1H-detected pulsed field gradient-stimulated echo (PFG-STE) NMR defined the molecular weights of ionic reactive complexes. This data and DFT charge distribution calculations suggest close ion pairs (CIPs) or tight ion pairs (TIPs) control alkylation selectivity in THF and solvent-separated ion pairs (SIPs) are the reactive species in DMSO.

-
A new series of spiropyrrolidine compounds containing indole/indazole moieties as side chains have been accomplished via a one-pot multicomponent synthesis. The method uses the 1,3-dipolar cycloaddition reaction between N-alkylvinylindole/indazole and azomethine ylides, prepared in situ from cyclic/acyclic amino acids. The 1,3-dipolar cycloaddition proceeds efficiently under thermal conditions to afford the regio- and stereospecific cyclic adducts.
