Photobase generator

The object of the present invention is to provide a photobase generator capable of efficiently generating amines (tertiary amines and amidine) high in catalytic activity by sensing light with a wavelength of from 350 to 500 nm (especially, from 400 to 500 nm). The present invention is a photobase generator characterized in being represented by general formula (1) or (2). Y+ is a quaternary ammonio group of general formula (3) to (5), and X? is a counter anion selected from among a borate anion, a phenolate anion, and a carboxylate anion.

Synthesis and antitumor activity of some new 2-chloroethylnitrosoureas

The synthesis of a series of N-(2-chloroethyl)-N'-(9H-xanthen-9-yl)-N-nitrosoureas and N-(2-chloroethyl)-N'-(9H-thioxanthen-9-yl)-N-nitrosoureas is described. The title compounds were evaluated against NSCLCN6 L16 bronchial epidermoid carcinoma in vitro and some of them were found to be active. N-(2-chloroethyl)-N'-(2-methoxy-9H-xanthen-9-yl)-N-nitrosourea (8e) was active against leukemia P388 tumor system in mice.
