The first totalsynthesis of leopolic acid A, a fungal metabolite with a rare 2,3-pyrrolidinedione nucleus linked to an ureido dipeptide, was designed and carried out. Crucial steps for the strategy include a Dieckmann cyclization to obtain the 2,3-pyrrolidinedione ring and a Wittig olefination to install the polymethylene chain. An oxazolidinone-containing leopolic acid A analogue was also synthesized
Aurora kinase A inhibitors: Identification, SAR exploration and molecular modeling of 6,7-dihydro-4H-pyrazolo-[1,5-a]pyrrolo[3,4-d]pyrimidine-5,8-dione scaffold
Tricyclic 6,7-dihydro-4H-pyrazolo[1,5-a]pyrrolo[3,4-d]pyrimidine-5,8-dione was identified as a novel scaffold for Aurora kinase A inhibition through virtual screening. SAR exploration coupled with molecular modeling of 8a reveals the minimum pharmacophore requirements for Aurora kinase A inhibition. (c) 2008 Elsevier Ltd. All rights reserved.
