The above compounds are useful intermediates in producing testosterone 5α-reductase inhibitors which are useful topically for treatment of acne, seborrhea, female hirsutism, and systemically in treatment of benign prostatic hypertrophy.
专利号:US-2011015119-A1 优先权日:2009-06-24 标题:Novel semi-synthetic glycopeptides as antibacterial agents 发明人:CHU DANIEL; YE TAO; WANG BING 权利人:LEAD THERAPEUTICS INC 摘要:Semi-synthetic glycopeptides having antibacterial activity are described, in particular, the semi-synthetic glycopeptides described herein are made by chemical modification of a glycopeptide (Compound A, Compound B, Compound H or Compound C) or monosaccharide made by hydrolyzing the disaccharide moiety of the amino acid-4 of the parent glycopeptide in acidic medium to give the amino acid-4 monosaccharide; conversion of the monosaccharide to the amino-sugar derivative; acylation of the amino substituent on the amino acid-4 amino-substituted sugar moiety on these scaffolds with certain acyl groups; and conversion of the acid moiety on the macrocyclic ring of these scaffolds to certain substituted amides. Key reaction is the treatment of properly protected intermediate compound with isocyanate. Also provided are methods for the synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.

专利号:US-5596020-A 优先权日:1993-06-25 标题:Amino bi- and tri-carbocyclic alkane bis-aryl squalene synthase inhibitors 发明人:MORRIS ROBERT L; NEUENSCHWANDER KENT W; LEARN KEITH S; SCOTESE ANTHONY C 权利人:RHONE POULENC RORER PHARMA 摘要:This invention relates to a class of novel amino bi- and tri-carbocyclic alkane compounds having bis-aryl substitution which exhibit squalene synthase inhibition properties. The bi- and tri-carbocyclic alkane ring contains an amino group and the ring is further linked or bridged to two mono- and/or bicyclic rings. Compounds of this invention reduce levels of serum cholesterol in the body without significantly reducing mevalonic metabolite synthesis. This invention relates also to pharmacological compositions and method of treatment for lowering serum cholesterol levels using the compounds of this invention.
