A series of nonsecosteroidal vitamin D-3 receptor (VDR) ligands with phenyl-pyrrolyl pentane skeleton were synthesized for cancer therapy. In contrast to 1 alpha,25-dihydroxyvitamin D-3 (Calcitriol), these VDR ligands exhibited anti-proliferative activity without inducing hypercalcemia. These compounds were evaluated for vitamin D-3-agonistic ability and anti-proliferative activity in vitro. Among them, compounds 5k and 5i exhibited equivalent vitamin D-3-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 mu M, 0.176 mu M, and 1.01 mu M (Calcitriol: 5.58 mu M, 80.83 mu M and 4.46 mu M) respectively. Compound Si inhibited proliferation of PC-3 with IC50 value of 0.00798 mu M (Calcitriol: 17.25 mu M). Additionally, neither of these compounds significantly elevated serum calcium in rats.
