The biguanide–sulfonamide derivatives: synthesis, characterization and investigation of anticholinesterase inhibitory, antioxidant and DNA/BSA binding properties
ABSTRACT 1-Aryl-4,6-diamino-1,2-dihydro-1,3,5-triazines bearing diverse substituents at C2 and on the aromatic ring have been synthesized in good yield from an acid-catalyzed reaction between corresponding arylbiguanide and carbonyl compound in the presence of triethyl orthoacetate as a water scavenger.

which suggested lysophosphatidicacidacyltransferaseβ (LPAAT-β) as a possible target for this aminotriazine as well as several analogues identified by structure-activity relationship profiling. LPAAT-β inhibition (IC50 ≈15 nm) was confirmed in a biochemical assay and by its effects on cell proliferation in comparison with a known LPAAT-βinhibitor. These experiments illustrate the value of target-prediction

cyclic analogue L 2 were synthesized as hydrochloride or hydroperchlorate salts and their structures were characterized by spectroscopic and analytical methods. The solid state structures of L 1 .HCl and L 2 .2HClO 4 were determined by single crystal X-ray diffraction studies. X-ray data revealed that the asymmetric unit of L 1 .HCl contains two mono-protonated biguanidium units and two chloride anions
Synthesis of Solution-Phase Combinatorial Library of 4,6-Diamino-1,2-dihydro-1,3,5-triazine and Identification of New Leads Against A16V+S108T Mutant Dihydrofolate Reductase of Plasmodium falciparum
An efficient method to synthesize solution-phase combinatorial library of 1-aryl-4,6-diamino-1,2-dihydro-1,3,5-triazine was developed. The strategy involved an acid-catalyzed cyclocondensation between arylbiguanide hydrochlorides and carbonyl compounds in the presence of triethyl orthoacetate as water scavenger. A 96-membered combinatorial library was constructed from 6 aryl biguanides and 16 carbonyl compounds. Screening of the library by iterative deconvolution method revealed two candidate leads which are equally active against wild-type Plasmodium falciparum dihydrofolate reductase, but are about 100-fold more effective against the A16V + S108T mutant enzyme as compared to cycloguanil.
