    摘要: 2-Phenyl-4(3H)-quinazolones bearing a urethane or thiourethane group on the 2-phenyl substituent, a second urethane or thiourethane group on the benzo ring of the quinazolone nucleus and an alkyl, cycloalkyl or phenyl group in the 3-position are prepared by treating the corresponding bis-amino compound with an acid derivative or the corresponding bis(isocyanate) or bis(isothiocyanate) with an alcohol. The compounds, of which 2-[3'-(methoxycarbonylamino)-phenyl]-3-phenyl-6-methoxycarbonylamino-4-(3H)-quinazolone is a typical embodiment, are cytostatic agents.

    摘要: The invention relates to a process for the production of filaments and fibres having a moisture absorption of at least 7% and a water retention capacity of at least 25% by dry-spinning an acrylonitrile copolymer, containing more than 50 mval of carboxyl groups from a solvent, which contains 5 to 50% by weight of a compound with properties defined herein, washing the compound added to the solvent out of the freshly spun filaments and fibres and partly or completely converting the carboxyl groups into the salt form. The invention further relates to dry-spun filaments and fibres having a core and sheath structure, comprising a fibre-forming acrylonitrile copolymer having more than 50 mval of carboxyl and carboxylate groups and having a moisture absorption capacity of at least 7% and a water retention capacity of at least 25%.
