Formulation of liposome delivery system loaded with water insoluble 2-(4-(tetrahydro-2H-pyran-2-yloxy)-undecyl)-propane-1,3-diamminedichloroplatinum(II), LipoTHP–C11 was carried out. The particle size distributions were determined by dynamic light scattering and asymmetrical flow field-flow fra...

Herein we report the synthesis and biological activity of new sigma receptor (σR) ligands obtained by combining different substituted five-membered heterocyclic rings with appropriate σR pharmacophoric amines. Radioligand binding assay, performed on guinea pig brain membranes, identified 25b (...

An efficient solid phase synthesis of pyrrolidine carbamate nucleic acids is reported. The protected (2S, 4S)-4-aminopyrrolidine-2-methanol with nucleobases thymine and cytosine attached to the ring nitrogen through an acetyl linker can be activated as nitrophenyl carbonates for the synthesis of...

Unexpected substituent-dependent regioselectivty challenges in the synthesis of C-benzylated (N-arylcarbamoyl)phosphonate esters have been resolved. The C-benzylated N-furfurylcarbamoyl derivative showed low micromolar PfLDH inhibition, while one of the C-benzylated N-arylcarbamoyl analogues was...

Two non-chiral copper(II) complexes equipped with bis(β-cyclodextrin)s (bisCDs) were explored as hydrolase models for the enantioselective hydrolysis of two pairs of alkyl chain-possessing amino acid ester enantiomers. The two bisCD complexes are pyridine-linked with different CD cavity orienta...

A novel enzyme like polymer catalyst with imidazole moiety has been fabricated on multiwalled carbon nanotubes (MWCNT) by molecular imprinting technology.
