Novel nonsecosteroidal VDR ligands with phenyl-pyrrolyl pentane skeleton for cancer therapy.

چکیده
A series of nonsecosteroidal vitamin D3 receptor (VDR) ligands with phenyl-pyrrolyl pentane skeleton were synthesized for cancer therapy. In contrast to 1α,25-dihydroxyvitamin D3 (Calcitriol), these VDR ligands exhibited anti-proliferative activity without inducing hypercalcemia. These compounds were evaluated for vitamin D3-agonistic ability and anti-proliferative activity in vitro. Among them, compounds 5k and 5i exhibited equivalent vitamin D3-agonistic activity compared with Calcitriol. Meanwhile, compound 5k displayed promising inhibiting profile against MCF-7, HepG-2 and Caco-2 with IC50 values of 0.00586 μM, 0.176 μM, and 1.01 μM (Calcitriol: 5.58 μM, 80.83 μM and 4.46 μM) respectively. Compound 5i inhibited proliferation of PC-3 with IC50 value of 0.00798 μM (Calcitriol: 17.25 μM). Additionally, neither of these compounds significantly elevated serum calcium in rats.

متن کاملCarborane-based design of a potent vitamin D receptor agonist.
The vitamin D nuclear receptor (VDR) is a potential target for cancer therapy. It is expressed in many tumors and its ligand shows anticancer actions. To combine these properties with the application of boron neutron capture therapy (BNCT), we design and synthesize a potent VDR agonist based on the skeleton of the hormone 1α,25-dihydroxyvitamin D3 (1,25D) and an o-carborane (dicarba-o-closo-1,2...
