肝纤维化的特征是细胞外基质(ECM)成分过多沉积,并导致肝功能受损。维生素D在肝纤维化的发展中起关键作用,因为它抑制转化生长因子β1(TGFβ1)诱导的肝星状细胞(HSC)中ECM的过度沉积。在这里,设计和合成了一系列具有苯基-吡咯烷基戊烷骨架的新型非甾体维生素D受体(VDR)激动剂。其中,包括15a在内的7种化合物在胶原蛋白沉积和纤维化基因表达中表现出更有效的抑制活性。组织学检查结果表明,化合物15a处理可防止由四氯化碳(CCl 4)注射到小鼠体内。此外,与阳性对照卡泊三醇和1,25(OH)2 D 3不同,化合物15a不会引起对神经,心脏和许多其他器官有毒的高钙血症。这些发现为使用非类固醇VDR调节剂治疗肝纤维化的药物发现提供了新颖的见解。
Further Developments of the Phenyl-Pyrrolyl Pentane Series of Nonsteroidal Vitamin D Receptor Modulators as Anticancer Agents
摘要:
The vitamin D (3) receptor (VDR), which belongs to the nuclear-receptor superfamily, is a potential molecular target for anticancer-drug discovery. In this study, a series of nonsteroidal vitamin D mimics with phenyl-pyrrolyl pentane skeletons with therapeutic potentials in cancer treatment were synthesized. Among them, 11b and 11g were identified as the most effective agents in reducing the viability of four cancer-cell lines, particularly those of breast-cancer cells, with IC50 values in the submicromolar-concentration range. In addition, 11b and 11g possessed VDR-binding affinities and displayed significant partial VDR-agonistic activities determined by dual-luciferase-reporter assays and human-leukemia-cell-line (HL-60)-differentiation assays. Furthermore, 11b and 11g inhibited tumor growth in an orthotopic breast-tumor model via inhibition of cell proliferation and induction of cell apoptosis. More importantly, 11b and 11g exhibited favorable pharmacokinetic behavior in vivo and did not increase serum calcium levels or cause any other apparent side effects. In summary, 11b and 11g act as novel VDR modulators and may be promising candidates for cancer chemotherapy.

agonistic activities. Especially, compound 19f displayed the most anti-proliferativeactivities against MCF-7 and PC-3 cells with the IC50 values of 1.80 and 5.35μM, respectively, which was comparable to positive control 1,25-(OH)2D3. Moreover, compound 19f exhibited reduced toxicity against human normal liver cell line (L02) compared with the parental compound 7. Besides, the preliminary structure-activity

In order to find the vitamin D receptor (VDR) ligand whose VDR agonistic activity is separated from the calcemic activity sufficiently, novel nonsecosteroidal analogs with phenyl pyrrolyl pentane skeleton were synthesized and evaluated for the VDR binding affinity, antiproliferative activity in vitro and serum calcium raising ability in vivo (tacalcitol used as control). Among them, several compounds showed varying degrees of VDR agonistic and growth inhibition activities of the tested cell lines. The most effective compound 2g (EC50: 1.06 nM) exhibited stronger VDR agonistic activity than tacalcitol (EC50: 7.05 nM), inhibited the proliferations of HaCaT and MCF-7 cells with IC50 of 2.06 mu M and 0.307 mu M (tacalcitol: 2.07 mu M and 0.057 mu M) and showed no significant effect on serum calcium.
