PB28dihydrochloride性质、用途与生产工艺
PB28 是一种环己基哌嗪衍生物，是一种 Ki 值为 0.68 nM 的高亲和力和选择性 sigma 2 (σ2) 受体激动剂。PB28 也是一种 σ1 受体拮抗剂，Ki 为 0.38 nM，对其他受体的亲和力较小。PB28 抑制豚鼠膀胱和回肠中的电诱发抽搐，其 EC50 值分别为 2.62 μM 和 3.96 μM。PB28 可以调节 SARS-CoV-2-人之间的蛋白质与蛋白质的相互作用。PB28 可诱导非 caspase 依赖性的细胞凋亡 (apoptosis)，并具有抗肿瘤活性。
Ki: 0.68 nM (σ2 receptor); 0.38 nM (σ1 receptor)
PB28 (15-25 nM; 24-48 hours; MCF7 and MCF7 ADR cells) treatment shows an accumulation in the G0-G1 phase for MCF7 and MCF7 ADR cells that are time and concentration independent.
PB28 has a higher σ2 receptor affinity expressed as K
i
(0.28 nM and 0.17 nM in MCF7 and MCF7 ADR cells, respectively) than σ1 receptor affinity (13.0 nMand 10.0 nM, respectively).
PB28 inhibits cell growth of MCF7 and MCF7 ADR cells with IC
50
s of 25 nM and 15 nM, respectively after 2-day treatment.
PB28 induces apoptosis through a caspase-independent pathway.
PB28 also reduces P-gp expression in a concentration- and time-dependent manner (approximately 60% in MCF7 and 90% in MCF7 ADR).
PB28 displays antiproliferative and cytotoxic effects in both C6 rat glioma and SK-N-SH human neuroblastoma cell lines.
