vitamin D(3) analogs having a lactam structure in their side chains, 1 alpha,25-dihydroxyvitamin D(3)-26,23-lactams (DLAMs), were designed based on the principle of regulation of the folding of helix-12 in the vitamin D nuclear receptor (VDR). The new analogs were synthesized via 1,3-dipolar cycloaddition reaction and subsequent reduction of the isoxazolidine as key steps. Among the analogs, (23S,25S)-DLAM-01
根据调节螺旋结构折叠原理,设计了在侧链具有内酰胺结构的新型维生素D(3)类似物1α,25-二羟基维生素D(3)-26,23-内酰胺(DLAM)。维生素D 12核受体(VDR)中。通过1,3-偶极环加成反应和随后还原异恶唑烷作为关键步骤合成了新的类似物。在类似物中,(23S,25S)-DLAM-01(4a)和(23S,25S)-DLAM-1P(5a)与VDR牢固结合。此外,发现这些类似物可抑制由1 alpha,25-dihydroxyvitamin D(3)诱导的HL-60细胞的分化。
