摘要 |
<p>Phenyl maleic anhydride and maleimide derivatives (I) are new. Phenyl maleic anhydride and maleimide derivatives of formula (I), are new. [Image] X : N or O; R 11-10C alkoxy, 2-10C alkenyloxy or 2-10C alkynyloxy; R 2H, 1-10C alkyl, 2-10C alkenyl or 2-10C alkynyl, and R 3H or OH or is absent when X is O. Independent claims are also included for: (1) a mixture produced by extracting Antrodia camphorata mycelium with an aqueous or organic solvent; (2) Antrodia camphorata mycelium containing (I). ACTIVITY : Hypotensive; Antilipemic; Hepatotropic; Antiinflammatory; Cytostatic. In a test, 3-isobutyl-4-(4-(3-methyl-2-butenyloxy)phenyl)-1H-pyrrole-2,5-dione had an EC 50 value of 3.6 mu g/ml against Lewis lung carcinoma cells, compared with 0.14 mu g/ml for adriamycin. MECHANISM OF ACTION : Central cholinergic agonist.</p> |
