Discovery of thiochroman derivatives bearing a carboxy-containing side chain as orally active pure antiestrogens
摘要:
In order to search for alternatives to the sulfoxide moiety in the long side chain of pure antiestrogens, several molecules that may interact with water in a fashion similar to ICI164,384 were designed and it was found that compounds with the carboxy, the sulfamide, or the sulfonamide instead of the sulfoxide moiety also functioned as pure antiestrogens. Interestingly, the compound possessing the carboxy moiety showed superior antiestrogen activity compared to ICI182,780 when dosed orally. Results of the pharmacokinctic evaluation indicated that the potent antiestrogen activity at oral dosing attributed to both the improved absorption from the intestinal wall and the metabolic stability of the compound in liver.

The present invention relates to substituted 7H-dibenzo[b,g][1,5]dioxocin-5-one-derivatives, to processes for their preparation and to their use in medicaments, in particular as inhibitors of the cholesterol ester transfer protein (CETP) for the treatment and/or prevention of cardiovascular disorders, in particular hypolipoproteinaemia, dyslipidaemias, hypertriglyceridaemias, hyperlipidaemias and arteriosclerosis.
A novel and efficient S-arylation of sulfenamides with diaryliodonium salts for the synthesis of sulfilimines is developed. The reaction proceeds smoothly under transition-metal-free and air conditions, giving rapid access to sulfilimines in good to excellent yields via selective S–Cbondformation. This protocol is scalable and exhibits a broad substrate scope, good functional group tolerance, and
