Nemadipine A is an L-type calcium channel blocker that induces morphological and growth defects in wild-type C. elegans and those with hypoexpression of egl-19, which encodes the only L-type calcium channel α1-subunit in the C. elegans genome. It also inhibits L-type calcium channels in chick ciliary neurons. Nemadipine A increases TRAIL-induced cytotoxicity and synergistically enhances caspase-8 and caspase-3 activation in a concentration-dependent manner in H1299 lung adenocarcinoma cells. It also decreases Survivin expression when used alone or in combination with TRAIL in A549 cells.
Potent bombesin receptor agonist (IC50 values are 0.26, 1.55 and 2.52 nM for BB1, BB2 and BB3 respectively). Enhances glucose transport in obese and diabetic primary myocytes. Also stimulates NCI-H1299 lung cancer cell proliferation in vitro.
