Synthesis of some polyhydroxylated pyrrolidine derivatives.
Polyhydroxylated pyrrolidine, piperidine, and indolizidine alkaloids are of great interest because of their specific glycosidase inhibitory activity." Moreover, it has recently been found in our laboratories that swainsonine (1), a representative of the polyhydroxylated indolizidine alkaloids, has an immunostimulating activity, possibly as a result of its glycosidase inhibitory activity.21 This...
متن کاملSynthesis and antihyperglycemic activity of erythrose, ribose and substituted pyrrolidine containing thiazolidinedione derivatives.
A series of erythrose, ribose, and substituted pyrrolidine containing 2,4-thiazolidinediones were synthesized. Among them, thirteen unsaturated thiazolidinediones, six saturated thiazolidinediones and two unsaturated malonates were evaluated for their ability to enhance glucose utilization in cultured L6 myocytes. On the basis of the in vitro activity, 5-[4-[2-(1-benzyl-3,4-bis-benzyloxypyrroli...
متن کاملSynthesis, Semiempirical, Stereoselectivity and Pharmacological Activity of a New Class of Spiro Pyrrolidine and Isoquinoline Derivatives
1,3-Dipolar cycloaddition of azomethine ylides derived from acenaphthylene-1,2-dione and 5methyl-benzo[b]-thiophene-2,3-dione with L-proline, thiazolidine-4-carboxylic acid and 1,2,3,4tetrahydroisoquinoline-3-carboxylic acid with various electron deficient dipolarophiles leads to the formation of novel spiroheterocycles having two or more chiral centers. Semiempirical studies have been performe...
متن کاملAn efficient strategy for the synthesis of polysubstituted chromeno[4,3-b]pyrrolidine derivatives.
A powerful cascade reaction was developed for the synthesis of chromeno[4,3-b]pyrrolidines with high yields and excellent stereoselectivities. This efficient cascade reaction expeditiously established two fused rings which bear three contiguous stereogenic centers including one quaternary stereocenter in a single operation with low catalyst loading under mild conditions.
متن کاملDesign, synthesis and preliminary evaluation of novel pyrrolidine derivatives as matrix metalloproteinase inhibitors.
A series of novel pyrrolidine derivatives were designed, synthesized and assayed for their inhibitory activities on matrix metalloproteinase 2 (MMP-2) and aminopeptidase N (AP-N). The results showed that these pyrrolidine derivatives exhibited highly selective inhibition against MMP-2 as compared with AP-N. The hydroxamates 8a-c were equally or more potent MMP-2 inhibitors than the positive con...
