Various kinds of water-soluble 9-acyloxyellipticine derivatives were synthesized in a search for compounds with potent antitumor activity. Antitumor activities against several tumors in mice (P388 leukemia, colon 26, Lewis lung carcinoma and B16 melanoma) were evaluated by using intravenous administration. Many compounds exhibited good antitumor activities; in particular, the glutarate derivative (5o) showed potent antitumor activity. This comopound (5o) may be converted to 9-hydroxyellipticine (2) by enzyme-catalyzed hydrolysis in the body.

nomethyl-1H-benzoimidazol-2-yl)-propionic acid (1) displayed an IC(50) value of 7.1 nM in the [3H]CPP binding assay and an ED(50) value of 0.13 mg/kg (ip) in the NMDA lethality model. Compound 1, when administered intravenously as a single bolus dose of 3 mg/kg following permanent occlusion of the middle cerebral artery in the rat, reduced the volume of infarcted brain tissue by 45%.

A novel class of heterocyclic aromatic amino acids based on the 3-(2-benzimidazolyl)alanine system has been generated by chiral synthesis from D- or L-aspartic acid. The use of variously substituted o-phenylenediamines for condensation with the beta-carboxyl function of alpha-benzyl N-(benzyloxycarbonyl)-D-aspartate has led to a series of amino acids of graded hydrophobicity with a steric bulk similar
