HA-1077 suppress both proliferation of vascular smooth muscle cells and c-fos mRNA induction

Jpn Circ J. 1992 Dec;56(12):1229-33. doi: 10.1253/jcj.56.1229.

Abstract

HA1077 is a newly synthesized vasodilator with unique intracellular calcium antagonistic action. In this study, its effect on the growth of vascular smooth muscle cells (VSMC) stimulated by fetal calf serum was examined. Both the proliferation and [3H]thymidine incorporation into DNA of the growth-arrested VSMC was dose-dependently inhibited by HA1077. The expression of a proto-oncogene, c-fos, which reached the maximum 30 min after addition of serum, was similarly inhibited by this agent in a dose-dependent manner. Thus, HA1077 is expected to be a useful vasodilator agent capable of suppressing the growth of VSMC which is thought to be an important underlying mechanism of atherosclerosis or restenosis after angioplasty.
