2-Chloro-4,6-diamino-s-triazine (CAAT) is a metabolite of atrazine biodegradation in soils. Atrazine chlorohydrolase (AtzA) catalyzes the dechlorination of atrazine but is unreactive with CAAT. In this study, melamine deaminase (TriA), which is 98% identical to AtzA, catalyzed deamination of CAAT to produce 2-chloro-4-amino-6-hydroxy-s-triazine (CAOT). CAOT underwent dechlorination via hydroxya...

Cell-free extracts of Rhodococcus corallinus NRRL B-15444R dechlorinated deethylsimazine (2-chloro-4-ethylamino-l,3,5-triazine-6-amine) to N-ethylammeline (2-amino-4-ethylamino-l,3,5-triazine-6(SH)-one) anaerobically, and, thus, presumably hydrolytically. Two enzyme fractions (M, about 450000 and 180000) that dechlorinated deethylsimazine were detected after gel permeation chromatography of cel...

The kinetics o f inhibition o f photosystem II electron transfer by different diuron-like herbi­ cides (ureas, triazines, triazinones. biscarbam ates, uraciles) were studied, mainly by chloro­ phyll fluorescence measurem ents. Uracil derivatives and cyanazine, a particu lar triazine, were the slowest acting com pounds. The half-times o f action were strongly tem perature-dependent and were o f ...

Reaction of 1-aryl-2-hydrazono-imidazolidines with ethyl oxamate furnished novel derivatives of imidazo [2,1-c][1,2,4] triazine.

Polyamine biosynthesis and function has been shown to be a good drug target in some parasitic protozoa and it is proposed that the pathway might also represent a target in the malaria parasite Plasmodium falciparum. A series of 1,3,5-triazine-substituted polyamine analogues were tested for activity against Plasmodium falciparum in vitro. The series showed activity against the parasites and were...

A covalent triazine framework (CTF) with embedded polymeric sulfur and a high sulfur content of 62 wt % was synthesized under catalyst- and solvent-free reaction conditions from 1,4-dicyanobenzene and elemental sulfur. Our synthetic approach introduces a new way of preparing CTFs under environmentally benign conditions by the direct utilization of elemental sulfur. The homogeneous sulfur distri...

The title compound, C(17)H(16)ClN(5)·C(3)H(7)NO, was prepared by reaction of p-toluidine with 2,4,6-trichloro-1,3,5-triazine at room temperature. The dihedral angles between the triazine ring and the pendant rings are 3.61 (12) and 53.11 (12)°. An intra-molecular C-H⋯N inter-action occurs. The packing is stabilized by N-H⋯N and N-H⋯O hydrogen bonds and C-H⋯π and π-π [centroid-centroid distance ...

A blue-fluorescence 2,4,6-tris(4-fluorophenyl)-1,3,5-triazine (TFPT) monomer was synthesized with high yield and high purity under mild reaction conditions. The TFPT, which had three active fluoric groups, was facilely incorporated into stable cross-linked fluorescent polymeric nanoparticles (FCPNs) via precipitation polymerization with 6-(4-hydroxyphenyl)pyridazin-3(2H)-one (HPZ). The FCPNs we...

In the title compound, C(8)H(10)Cl(2)N(4)O, the dichloro-substituted triazine ring and the quasi-plane of the five-membered dimethyl-substituted oxazolidine unit, in which the O atom lies 0.228 (1) Å out of the least-squares plane, are close to being coplanar [dihedral angle = 4.99 (10)°]. In the crystal, mol-ecules are linked by inter-molecular C-H⋯Cl inter-actions, forming chains extend along...

Bisamides are key fragments for the introduction of gem-diaminoalkyl residues into retroinverso pseudopeptide derivatives and in the synthesis of peptidomimetic compounds. The literature methods for these types of compounds have certain drawbacks. In particular, when amides react with electrophile-activated DMSO, the yields are rather low. We have found new electrophiles, 2,4,6-trichloro[1,3,5]...
