Abstract
A series of macrocyclic PKCθ inhibitors based on a 1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one hinge binder has been studied. Different aromatic and heteroaromatic substituents have been explored in order to optimize potency, isoform selectivity as well as DMPK properties. The importance of the length of the macrocyclic linker has also been analyzed. In particular, it has been found that methyl substitutions on the linker can have a profound influence on both potency and metabolic stability. Several compounds showing very good profiles, suitable for in vivo testing, are disclosed.

LFZ-4-46, a tetrahydroisoquinoline derivative, induces apoptosis and cell cycle arrest via induction of DNA damage and activation of MAPKs pathway in cancer cells. Anticancer Drugs 2021; 32:842-854. [PMID: 33929988 PMCID: PMC8366768 DOI: 10.1097/cad.0000000000001077] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 03/19/2021] [Indexed: 01/20/2023]
Abstract
LFZ-4-46, that is [2-hydroxy-1-phenyl-1,5,6,10b-tetrahydropyrazolo(5,1-a) isoquinolin-3(2H)-yl](phenyl) methanone, a tetrahydroisoquinoline derivative with a pyrazolidine moiety, was synthetically prepared. The anti-cancer mechanism of the compound has not been clarified yet. In this study, the anticancer effects and potential mechanisms of LFZ-4-46 on human breast and prostate cancer cells were explored. (a) 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazoliumbromide assay was first performed to detect the effects of LFZ-4-46 on the viability of human cancer cells. (b) Comet assay was utilized to evaluate DNA damage. (c) Cell cycle, apoptosis and mitochondrial membrane potential were detected by flow cytometry. (d) The expression of relative proteins was detected by western blotting assay. LFZ-4-46 significantly inhibited the viability of cancer cells in a time- and dose-dependent manner and had no obviously inhibitory effect on the viability of mammary epithelial MCF-10A cells. Mechanistic studies demonstrated that LFZ-4-46-induced cell apoptosis and cycle arrest were mediated by DNA damage. It caused DNA damage through activating γ-H2AX and breaking DNA strands. Further studies showed that mitogen-activated protein kinasess pathway was involved in these activated several key molecular events. Finally, LFZ-4-46 showed a potent antitumor effect in vivo. These results suggest that LFZ-4-46 may be a potential lead compound for the treatment of breast and prostate cancer.
