saturated pyran ring structure, were markedly less active or inactive as photosensitizers. NDH2476 was found to intercalate and damage DNA following UVA light treatment as determined by plasmid DNA unwinding and nicking experiments. Taken together, these data demonstrate that an intact furan ring in psoralen photosensitizers is not required for keratinocyte growth inhibition or DNA damage. Our findings
光敏剂用于治疗牛皮癣和白癜风等表皮增殖和分化障碍。在这些研究中,线性补骨脂素(呋喃[3,2-g]苯并吡喃-7-one)类光敏剂的扩环碳同系物4,10-二甲基-2H,8H-苯并[1,2-b :5,4-b']dipyran-2-one (NDH2476),被合成并分析其生物活性。在被紫外线(UVA,320-400 nm)激活后,发现 NDH2476 是角质形成细胞生长的有效抑制剂(IC50 = 9 nm)。在吡喃环中甲基化或含有饱和吡喃环结构的类似衍生物作为光敏剂的活性明显较低或无活性。根据质粒 DNA 解旋和切口实验确定,在 UVA 光处理后,发现 NDH2476 嵌入并损伤 DNA。综合起来,这些数据表明补骨脂素光敏剂中完整的呋喃环不是角质形成细胞生长抑制或 DNA 损伤所必需的。我们发现低纳摩尔浓度的苯并吡喃酮衍生物作为光敏剂具有活性,这表明该化合物或结构相关的化合物可用于治疗涉及异常表皮细胞生长和分化的皮肤病。

3-triazoles were effectively synthesized via copper-assisted cycloaddition of mono- and/or di-alkyne chromenone derivatives 2a and b and 9 with several sulfa drug azides 4a–d and 6. The resulting molecular derivatives were tested for cytotoxicity againstprostate and breast cancer cells. Among the derivatives, 10a, 10c, and 10e exhibited potent cytotoxicity against PC-3 cells with IC50 values of 2.08,
