摘要:
The present invention provides substituted azetidinone compounds of formula (IA), formulations and processes for preparing the same which can be useful for treating vascular conditions such as atherosclerosis or hypercholesterolemia, diabetes, obesity, stroke, demyelination and lowering plasma levels of sterols and/or stanols in a subject.
wherein A is -CH=CH-B; -C≡C-B; -(CH₂) p -X-B, wherein p is 0-2 and X is a bond, -NH- or-S(O)₀₋₂; optionally substituted heteroaryl or benzofused heteroaryl; -C(O)-B; or
wherein k is 1-2; D is B'-(CH₂) m C(O)-, wherein m is 1-5; B'-(CH₂) q -, wherein q is 2-6; B'-(CH₂) e -Z-(CH₂) r -, wherein Z is -O-, -C(O)-, phenylene, -NR₈- or -S(O)₀₋₂-, e is 0-5 and r is 1-5, provided that the sum of e and r is 1-6; B'-(alkenylene)-; B'-(alkadienylene)-; B'-(CH₂) t -Z-(alkenylene), wherein t is 0-3, provided that the sum of t and the number of carbon atoms in the alkenylene chain is 2-6; B'-(CH₂) f -V-(CH₂) g -, wherein V is cycloalkylene, f is 1-5 and g is 0-5, provided that the sum of f and g is 1-6; B'-(CH₂) t -V-(alkenylene) or B'-(alkenylene)-V-(CH₂) t -, provided that the sum of t and the number of carbon atoms in the alkenylene chain is 2-6; B'-(CH₂)a-Z-(CH₂)b-V-(CH₂)d-, wherein a, b and d are 0-6, provided that the sum of a, b and d is 0-6; T(CH₂) s -, wherein T is cycloalkyl and s is 1-6; naphthylmethyl or optionally substituted heteroarylmethyl; B is optionally substituted phenyl; B' is naphthyl, optionally substituted heteroaryl or optionally substituted phenyl; R is hydrogen, fluoro, alkyl, alkenyl, alkynyl, or B-(CH₂)h-, wherein h is 0-3; R4 is optionally substituted phenyl, indanyl, benzofuranyl, tetrahydronaphthyl, pyridyl, pyrazinyl, pyrimidinyl or quinolyl; are disclosed, as well as their use as hypocholesterolemic agents; the method of using compounds of the formula II
wherein R₂₀ is optionally substituted phenyl, optionally substituted naphthyl, optionally substituted heteroaryl, or optionally substituted benzofused heteroaryl, R₂₁, R₂₂ and R₂₃ are independently selected from H or R₂₀; E, F and G are independently a bond; cycloalkylene; alkylene; alkenylene; alkynylene; a substituted alkylene, alkenylene or alkynylene chain ; an interrupted alkylene, alkenylene or alkynylene chain ; or an interrupted alkylene, alkenylene or alkynylene chain substituted by one or more substituents; or one of R₂₁-E and R₂₂-F is selected from the group consisting of halogeno, OH, alkoxy, -OC(O)R₅, -NR₁₀R₁₁, -SH or -S(alkyl); R₅ is alkyl, phenyl, R₁₄-phenyl, benzyl or R₁₄-benzyl; R₁₀ and R₁₁ are independently selected from H and lower alkyl, or a pharmaceutically acceptable salt thereof, in a pharmaceutically aceptable carrier as hypocholesterolemic agents is also disclosed.
