were isolated from a tunicate as inhibitors of p53–Hdm2 interaction, a promising target for cancer chemotherapy. Their structures including the absolute configurations were elucidated to be new sulfonated serinol derivatives, each of which contains a 6,8-dioxabicyclo[3.2.1]octane unit and either glycerophosphocholine or glycerophosphoethanolamine moiety. They inhibited p53–Hdm2 interaction with IC50
从被膜中分离出丝氨酸丝氨酸A–L作为p53–Hdm2相互作用的抑制剂,这是癌症化疗的有希望的靶标。阐明了它们的结构,包括绝对构型,是新的磺化丝氨醇衍生物,其中每个均包含一个6,8-二氧杂双环[3.2.1]辛烷单元和甘油磷酸胆碱或甘油磷酸乙醇胺部分。它们以2.0–55μM的IC 50值抑制了p53–Hdm2的相互作用。其中,硅腺苷丝氨酸A和B表现出最强的抑制作用,IC 50值为2.0μM 。
