gem-Diphosphonate and gem-phosphonate-phosphate compounds with specific high density lipoprotein inducing activity
摘要:
New diphosphonate compounds and related derivatives were synthesized and investigated for their activity in specifically inducing plasma high density lipoproteins (HDL) and high density lipoprotein cholesterol (HDL-C) in normal rats. The screening of numerous compounds has permitted the determination of the structural variations leading to optimal plasma lipid altering activity, indicating antiatherosclerotic potential. Among the compounds observed to be the most active, dimethyl alpha-(dimethoxyphosphinyl)-p-chlorobenzyl phosphate (20, SR-202, mifobate) was selected for further pharmacological and subsequent clinical development.
Copper-mediated 1,4-Conjugate Addition of Boronic Acids and Indoles to Vinylidenebisphosphonate leading to<i>gem</i>-Bisphosphonates as Potential Antiresorption Bone Drugs
wide range of gem‐bisphosphonate tetraethyl esters as precursors for bisphosphonic acids, which are potent inhibitors of bone resorption, bearing alkyl, aryl, and indole substituents in the β position were prepared through the CuII‐catalyzed 1,4‐conjugate addition of boronicacids and indoles to vinylidenebisphosphonate tetraethyl ester.

Bisphosphonate ester 2 is an inhibitor of inflammation, but is devoid of antiarthritic effects. SAR studies on a series of related bisphosphonate esters resulted in compounds 6e, 6i, 6j, and 6m, which exhibited excellent inhibition of an arthritis model, in addition to potent anti-inflammatory effects.
