摘要


以生物活性爲指標從台灣產直立穗珊瑚(Nephthea erecta)分離得到五個固醇類化合物,分別爲:24-methylcholesta-5,24(28)-diene-3β,19-diol(1),24-methylcholesta-5,24(28)-diene-3β,19-diol-7β-monoacetate(2),24-methylcholesta-5,24(28)-diene-3β,7β,19-triol(3),and 24-methylcholesta-24(28)-ene-3β,5α,6β,19-tetraol(4),aswell as an inactive steroid,24-methylenecholesta-5,24(28)-diene-3β-ol(5)。生物活性分西析結果顯示化合物1,2,3,和4對人類直腸癌細胞(HT-29)、人類肺癌細胞(A-549)、人類口腔癌細胞(KB)、以及老鼠淋巴癌細胞(P-388)均具有強力之毒殺能力。

Bioassay-directed fractionation of the methylenechloride extracts of theFormosan soft coral Nephthea erecta has resulted in the isolation of four cytotoxic steroids,24-methylcholesta-5,24(28)-diene-3β,19-diol(1),24-methylcholesta-5,24(28)-diene-3β,19-diol-7β-monoacetate(2),24-methylcholesta-5,24(28)-diene-3β,7β,19-triol(3),and 24-methylcholesta-24(28)-ene-3β,5α,6β,19-tetraol(4),aswell as an inactive steroid,24-methylenecholesta-5,24(28)-diene-3β-ol(5)
