ChemInform Abstract
Derivatives (IV), (V), and, especially, (IIIb) are the most potent in vitro immunosuppressive compounds of a series of cyclolignans, e.g. (I) -(V), either isolated from Podophyllum resin, e.g. (I) and (II), or synthesized from (I) or (IIIa). Due to their better noncytotoxic activity, compounds (IV) and (V) are candidates for further in vivo evaluation.
