A first series of novel NH and N-alkyl-substituted cage dimeric 4-aryl- 1,4-dihydropyridines 3a-f has been synthesized and evaluated as HIV-1 protease inhibitors in in vitro assays. While the NH and N-methyl derivatives 3a,b,e,f were almost inactive with

Vascular endothelial growth factor-2 receptor (VEGFR-2) kinase is a promising target for the development of novel anticancer drugs. Molecular docking modeling was performed on a series of 4-aryl-1,4-dihydropyridines derivatives to evaluate the structural basis for VEGFR-2 inhibitory activity. Some 4-aryl-1,4-dihydropyridines were synthesized in the reaction of aromatic aldehydes and ethyl propiolate with anilines in acetic acid. The biological activities were evaluated against the cells A549, A431 and Hep-G2. The results indicated that 4-aryl-1,4-dihydropyridines could be the promising potential VEGFR-2 inhibitors.

We have successfully synthesized 3,4,5-substituted 1,4-dihydropyridines (1,4-DHPs) from amine hydrochloride salts, aldehydes, and acetals in good yields without the addition of a catalyst. The synthesized 1,4-DHPs exhibit various wavelengths of fluorescen

Design, synthesis and biological evaluation Of 3,9-Diazatetraasteranes as novel matrilysin inhibitors

Matrilysin is an ideal biological target to develop novel inhibitors because it is overexpressed in malignant tumour cells. A series of 3,9-diazatetraasteranes was designed as inhibitors of matrilysin, which was an ideal biological target because it is responsible for aggressive malignant phenotypes and poor prognoses implicated in many cancers. Docking simulation supported the initial pharmacophore hypothesis and suggested a common interaction mechanism of 3,9-diazatetraasteranes with the catalytic site of matrilysin. The 3,9-diazatetraasteranes were synthesized by the photocyclization of 4-aryl-1,4-dihydropyridines, and their structures were determined using 1H NMR, 13C NMR and MS. The inhibitory activities of these compounds on matrilysin were investigated in vitro using an MTT assay in A549 (small cell lung cancer) cells. The results show that the 3,9-diazatetraasteranes can inhibit the growth of A549 tumour cells. The best IC50 value is approximately 50 μm. This result indicates that 3,9-diazatetraasteranes will be useful pharmacological tools for the investigation of matrilysin inhibitors. A series of 3,9-diazatetraasteranes was designed and synthesized as matrilysin inhibitors. These compounds were evaluated for their inhibitory activity against A549 (small cell lung cancer) cells and displayed potent activities.

Synthesis and biological evaluation of first N-alkyl syn dimeric 4-aryl-1,4-dihydropyridines as competitive HIV-1 protease inhibitors

, p. 367 - 374 (2007/10/03)
A first series of novel N-alkyl substituted syn dimeric 4-aryl-1,4-dihydropyridines 12-17 have been synthesised and evaluated as HIV-1 protease inhibitors in in vitro assays. While the N-methyl derivatives 12 and 13 were almost inactive, with IC50-values of about 225 μM, the N-benzyl compounds with varied ester groups all exhibited stronger activities, with IC50-values of 11-12 μM for the presently best compounds 16 and 17 with ethyl ester functions. The type of HIV-1 protease inhibition of the novel inhibitors was characterised as competitive. With the increase of observed activity from N-methyl derivatives to N-benzyl compounds the binding mode may correspond to that of cyclic ureas with hydrophobic interactions of the four aromatic residues to the S1/S1′ and S2/S2′ regions of HIV-1 protease.
