Synthesis of diacetoxy acetal derivatives of santonin and their enhancing effects on HL-60 leukemia cell differentiation.
Several diacetoxy acetal analogues have been synthesized from santonin and assessed for their ability of inducing or enhancing the differentiation of human HL-60 leukemia cells. The compounds themselves had little effect on HL-60 cell differentiation. However, three analogues, 2a, 3a, and 5b, synergistically enhanced 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3]-induced HL-60 cell differentiation when combined with 5 nM of dihydroxyvitamin D3 [1,25-(OH)2D3], a well-known differentiation inducer. Especially, the compound 5b profoundly enhanced the 1,25-(OH)2D3]-induced HL-60 cell differentiation.
