gamma-Aminobutyric acid (GABA) analogues based on 4-amino-cyclopent-1-enyl phosphinic acid (34-42) and 3-aminocyclobutane phosphinic acids (51, 52, 56, 57) were investigated in order to obtain selective homomeric rho(1) GABA(C) receptor antagonists. The effect of the stereochemistry and phosphinic acid substituent of these compounds on potency and selectivity within the GABA receptor subtypes was investigated. Compounds of high potency at GABA(C) rho(1) receptors (36, K-B = 0.78 mu M) and selectivity greater than 100 times (41, K-B = 4.97 mu M) were obtained. The data obtained was analyzed along with the known set of GABA(C) rho(1) receptor-ligands, leading to the development of a pharmacophore model for this receptor, which can be used for in silico screening.
The application relates to a series of 2-imino-6-methylhexahydropyrimidin-4-one derivatives and 3-imino-5-methyl-l,2,4-thiadiazinane 1,1-dioxide derivatives of formula (I), substituted by an arylaminophenyl or heteroarylaminophenyl moiety. The compounds are potent inhibitors of the growth and propagation of the Plasmodium falciparum parasite in human blood and thus useful as pharmaceutical agents for the treatment of malaria.

An efficient copper‐catalyzed carbocyclization of silyl enol ether tethered ynamides has been developed, allowing rapid and practical construction of diverse 2‐azabicyclo[3.2.0] compounds in generally good to excellent yields with broad substrate scope under mild reaction conditions. Importantly, this protocol not only constitutes a rare example of non‐noble metal‐catalyzed alkyne carbocyclization
