Haloperidol metabolite II prodrug: Asymmetric synthesis and biological evaluation on rat C6 glioma cells
摘要:
In a previous work we reported the antiproliferative effects of (+/-)-MRJF4, a novel haloperidol metabolite II (HP-mII) (a sigma-1 antagonist and sigma-2 agonist) prodrug, obtained through conjugation to 4-phenylbutyric acid (PhBA) [a histone deacetylase inhibitor (HDACi)] via an ester bond. As a continuation of this work, here we report the asymmetric synthesis of compounds (R)-(+)-MRJF4 and (S)(-)-MRJF4 and the evaluation of their biological activity on rat C6 glioma cells, derived from glioblastoma multiforme (GBM), which is the most common and deadliest central nervous system (CNS) invasive malignancy. Favourable physicochemical properties, high permeability in the parallel artificial membrane permeability assay (PAMPA), good enzymatic and chemical stability, in vivo anticancer activity, associated with the capacity to reduce cell viability and to increase cell death by apoptosis, render compound (R)-(+)-MRJF4 a promising candidate for the development of a useful therapeutic for gliomas therapy.

metabolite II conjugated with the histone deacetylase (HDAC) inhibitor valproic acid, has previously demonstrated a promising antiangiogenic activity. Herein, the asymmetric synthesis of (R)-(+)-MRJF22 and (S)-(−)-MRJF22 was performed to investigate their contribution to (±)-MRJF22 antiangiogenic effects in human retinal endothelial cells (HREC) and to assess their therapeutic potential in primary
血管生成和血管内皮生长因子 (VEGF) 水平的增加导致葡萄膜黑色素瘤 (UM) 的转移和死亡率增加,这是一种成人眼部的侵袭性恶性肿瘤。(±)-MRJF22是与组蛋白去乙酰化酶 (HDAC) 抑制剂丙戊酸偶联的 σ (σ) 配体氟哌啶醇代谢物 II 的前药,之前已证明具有良好的抗血管生成活性。在此,进行了(R)-(+)-MRJF22和(S)-(-)-MRJF22的不对称合成,以研究它们对(±)-MRJF22的贡献人视网膜内皮细胞 (HREC) 的抗血管生成作用,并评估其在原发性人葡萄膜黑色素瘤 (UM) 92-1 细胞系中的治疗潜力。虽然两种对映异构体显示出与外消旋混合物几乎相同的降低细胞活力的能力,但(S)-(-)-MRJF22在内皮细胞和肿瘤细胞中表现出最高的抗迁移作用。鉴于细胞运动对癌症进展的基本贡献,(S)-(-)-MRJF22可能代表 UM 患者新型抗转移治疗的有希望的候选者。

The bis(carbonyl) manganese(I) complex [Mn(CO)2 (1)]Br (2) with a chiral (NH)2 P2 macrocyclic ligand (1) catalyzes the asymmetrictransferhydrogenation of polar double bonds with 2-propanol as the hydrogen source. Ketones (43 substrates) are reduced to alcohols in high yields (up to >99 %) and with excellent enantioselectivities (90-99 % ee). A stereochemical model based on attractive CH-π interactions
