Experimental techniques for testing the sensitivity of bladder tumours to antineoplastic drugs
1973
A number of laboratory tests can be employed to examine the sensitivity of human bladder tumour cells to various chemotherapeutic agents.-Their principles and methods, and some preliminary results, are described with special reference to certain in vitro and in vivo cytotoxicity tests and to heterotransplantation in the hamster. Satisfactory agreement has sometimes been observed between experimental results and clinical responses, but our experience is still very limited.-The employment of several such tests would probably lead to a greater degree of reliability in the laboratory assessment of the sensitivity of bladder tumours to cytotoxic drugs.
Papaverine in Human Bladder Muscle
1989
It is generally assumed that drugs which induce relaxation of smooth muscles may be of clinical importance in some urological disorders; such drugs are indeed widely used, for example, in the therapy of unstable bladders or to facilitate the passage of ureteral stones. Recently, papaverine has been shown to be very effective, e.g., in relaxing smooth muscles of the corpus cavernosum penis, thereby inducing erections in many impotent men (Virag 1982). The purpose of this study is to determine the relaxing properties of papaverine in isolated muscle strips from the human detrusor and to evaluate its potential clinical importance.
New potentially cytotoxic thiolatogold(I) complexes of 1,1′-bis(diphenylphosphino)ferrocene
1996
Abstract 1,1′-Bis[chlorogold(I) diphenylphosphino] ferrocene (1) was chosen as the starting material to synthesize new thiolato gold(I) complexes. This has been achieved by substituting the chlorine atoms by monofunctional and bifunctional thiolates affording ‘open’ thiolatogold complexes and trimetallic ferrocenophane-type structures, respectively. The new 1,1′-bis(2,6-dithia-1-phosphanyl)ferrocene (7) containing directly linked P and S atoms was also prepared but no gold complex was obtained. Compound 2 crystallizes in the monoclinic space group P21/n with a=10.2632), b=21.064(4), c=16.259(3) A , β=97.06(2)° and V=3.488(1) A 3 . The distance between the two gold atoms (3.06 A) indicates a…
