摘要:
The invention is in the field of biologically active compounds such as taxol-2'-adipate derivatives, derivatives of bergenin and erythromycin derivatives. Taxol-2'-adipate derivatives have anti-cancer activity analogous to taxol. Bergenin derivatives have angiotensin converting enzyme inhibiting activity, and are therefore useful in the treatment of hypertension. Erythromycin derivatives are useful as antibiotics.
