摘要:
An X-ray-intercepting gold complex of mono-L-aspartyl (or mono-L-glutamyl) chlorin e6 or a salt thereof is used in the therapy of the tumor, cancer or arteriosclerosis lesions by X-ray irradiation. The complex provides a sharp x-ray image of tumor, solid cancer or lesions of arteriosclerosis. A similar platinum complex may also be utilized.
摘要:
Novel PF 1022 derivatives--cyclodepsipeptides represented by the below-described formula (I)--and acid addition salts thereof, which have been synthesized according to the present invention, have anthelmintic activities against various parasitic worms which are parasitic on human bodies, domestic animals and pet animals. They are therefore useful as anthelmintics for the prevention or treatment of parasitic infections. ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, Q, X, Y and Z have been defined herein.
