A series of 4-aminoquinoline 1,3,5-triazine derivatives were synthesized and evaluated for anticancer activity against cancer cell lines HeLa, MCF-7, HL-60, HepG2 where these derivatives exert significant anticancer activity. The molecules found nontoxic against MCF-12A. The molecules also showed potent inhibition of EGFR-TK as compared to eroltinib in enzyme-based assay. The newly synthesized derivatives were screened for their in vitro antibacterial and antifungal activity against Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa and Candida albicans, Aspergillus niger, Aspergillus fumigatus using cefixime and fluconazole as standard. Antibacterial screening results suggest that compound 7c showed potent activity against S. aureus, P. aeruginosa, and P. vulgaris. In antifungal screening, compound 7b showed significant activity against A. niger, A. fumigatus and moderate activity against C. albicans.

A novel series of 1,3,5-triazine-thiazolidine-2,4-diones was synthesized and characterized by a number of analytical and spectroscopic techniques. The molecules were screened for the in vitro inhibition of dipeptidyl peptidase-4 and compound 7a showed the most prominent inhibition with IC50 = 6.25 μM. The other compounds showed considerable inhibition (IC50 = 12.11-49.21 μM). Docking studies indicated that the lipophilic thiazolidine-2,4-dione fragment of ligand 7a was oriented towards the tight lipophilic cavity of the S1 pocket of the active site formed by residues such as Tyr631, Val656, Trp659, Tyr662, Tyr666 and Val711 via the formation of H-bonds with Tyr547. One of the amines present on the wings of the triazine formed a hydrogen bond with Glu205, a vital residue for the N-terminal recognition site with an efficient CDOCKER interaction energy. In a bacterial inhibition study, the entire set of compounds showed excellent activity and, in some instances, were found to be equipotent to the cefixime used as a standard.

Impressed by the exceptional antibacterial activity exhibited by our earlier designed molecules originating from 1,3,5-triazine, the present study was undertaken to synthesize a novel series of 1,3,5-triazine-pyrazole conjugates to bring diversity around the core skeleton. The target analogues showed potent antibacterial activity against tested Gram-positive and Gram-negative microorganisms. The toxicity and metabolic site prediction studies were also held out to set an effective lead candidate for the future antibacterial drug discovery initiatives.

Bi-functional conjugates comprised of 4-aminoquinoline and 1,3,5-triazine were synthesized through facile synthetic routes. These compounds were rigorously screened for determination of their antimalarial activity against wild and mutant cultured Plasmodium falciparum. The results disclosed that the conjugates have considerable antimalarial activity against both wild and mutant parasites with marked variation on changing the pattern of substitutions. The observed activity profiles were additionally substantiated by docking studies on both wild and quadruple mutant P. falciparum dihydrofolate reductase thymidylate synthase (pf-DHFR-TS).

A series of hybrid 4-aminoquinoline 1,3,5-triazine derivatives was synthesized and their chemical structure were confirmed by 1H-NMR, 13C-NMR, FT-IR and mass spectrometric analyses. In vitro antimalarial activity of these compounds was evaluated against chloroquine-sensitive (3D-7) and chloroquine resistant (RKL-2) strains of P. falciparum. Results showed that all compounds had considerable antimalarial activity against both the strains and further docking studies were performed on both wild type (1J3I.pdb) and quadruple mutant (N51I, C59R, S108 N, I164L, 3QG2.pdb) pf-DHFR-TS to quantify the structural parameter necessary for the activity.

Some hybrid 1,3,4-thiadiazole-1,3,5-triazine derivatives tethered via -S- bridge were synthesized and characterized with the aid of spectroscopic and elemental analysis. These hybrid conjugates were then investigated for their antibacterial activity against selected Gram-positive and Gram-negative bacteria. Excellent to moderate antibacterial activity was presented by the target compounds.

Two novel series of s-triazine derivatives (6a-e and 7a-f) were synthesized with various aromatic and heterocyclic amines. The synthesized compounds were subsequently evaluated for their in vitro antibacterial activity against three gram-positive viz. Bacillus subtilis (NCIM- 2063), Bacillus cereus (NCIM-2156), Staphylococcus aureus (NCIM-2079) and gram-negative bacteria viz. Pseudomonas aeruginosa (NCIM-2036), Escherichia coli (NCIM-2065) and Klebseilla pneumoniae (NCIM-2706) by the broth dilution method as recommended by the National Committee for Clinical Laboratory Standards (NCCLS) using streptomycin as reference standard. Structures of the synthesized compounds were elucidated on the basis of elemental analyses and spectral data. Springer Science+Business Media, LLC 2010.

Desai,Dodiya,Trivedi,Shah
, p. 495 - 506 (2008/12/23)
Series of 2,4-diarylamino-6-[N-(3′-methylphenyl)dithiocarbamoyl]-s- triazines (4a-l) and 2,4-bis[N-(3′-methylphenyl)dithiocarbamoyl]-6- arylamino-s-triazines (7a-l) were synthesized by two different synthetic routes. In the first route (A), 2,4,6-tricholoro-s-triazine (1) was condensed with N-(3-methylphenyl)ammoniumdithiocarbamate to afford compounds 3 or 6, which on reaction with different aryl amines afforded compounds 4a-l or 7a-l. In the second route (B), condensation of 1 with different aryl amines yielded compounds 2a-l or 5a-l. On further treatment with N-(3-methylphenyl) ammoniumdithiocarbamate these afforded compounds 4a-l or 7a-l. The newly synthesized compounds 4a-l and 7a-l were characterized by elemental analyses, infrared (IR), and 1H nuclear magnetic resonance (NMR) spectroscopic investigation. All the products were evaluated for their antibacterial and antifungal activity.

Screening of a chemical library in a DNA helicase assay involving the Pseudomonas aeruginosa DnaB helicase provided a triaminotriazine inhibitor with good antibacterial activity but associated cytotoxicity toward mammalian cells. Synthesis of analogs provided a few inhibitors that retained antibacterial activity and demonstrated a significant reduction in cytotoxicity. The impact of serum and initial investigations toward a mode of action highlight several features of this class of compounds as antibacterials.

Condensation of 5-cyano-2-hydrazino-3-N-methyl-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin-4 -one (3a and 3b) with 2,4-bisalkyl/arylamino-6-chloro-s-triazine (4) gave the corresponding 2,4-bisalkyl/arylamino-6-[5′-cyano-3′-N-methyl]-6′-phenyl/p -chlorophenyl-3′,4′-dihydropyrimidin-4′-one-2′-yl-hyd razino-s-triazines (5a-n and 6a-n). The compounds 4 have been prepared by the condensation of cyanuric chloride and different alkyl/aryl amines. The reaction between 5-cyano-3-N-methyl-2-methylthio-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin- 4-one (2a and 2b) with hydrazine hydrate furnished 3a and 3b, respectively. The condensation of 6-phenyl/p-chlorophenyl/5-cyano-2-mercapto-3,4-dihydropyrimidin-4-one (1a and 1b) with methyl iodide yielded 2a and 2b, respectively. All the products have been evaluated in vitro for their antimicrobial activity against several microbes and antitubercular activity against Mycobacterium tuberculosis H37 Rv. Copyright
