[source] Amino Acid Derivatives, Part 4: Synthesis and Anti-HIV Activity of New Naphthalene DerivativesARCHIV DER PHARMAZIE, Issue 7 2010Nawar S. Hamad Abstract A new series of 2-(naphthalen-2-yloxy)- N -[(aryl-5-thioxo-4,5-dihydro-1H -1,2,4-triazol-3-yl)methyl] acetamides 5a,f was synthesized from naphthalene-derived glycine derivative 2 via the hydrazinoacetamide analogs 4a,f. Alternatively, treatment of 4a with H2SO4 afforded 2-(naphthalen-2-yloxy)- N -((5-(phenylamino)-1,3,4-thiadiazol-2-yl)methyl) acetamide 6a. Alkylation or sulphonylation of 5a afforded the S-alkylated derivatives 7 and 8, respectively. Interestingly, treatment of 3 with methoxide ion gave the triazine derivative 9. The synthesized compounds have been screened for their inhibitory activity against HIV-1 and HIV-2 in MT-4 cells. However, 7 was found to be the potent inhibitor in vitro for the replication of HIV-1 (EC50 = 0.20 ,g/mL), suggesting a new lead in the development of an antiviral agent.

Acylation of amidines 1 and cyclocondensation of the resulting carbamates 3 gave [1,3,5,7]tetrazocine-2,6-dione derivatives 4, and subsequent retro-ene reaction and ring contraction afforded triazine derivatives 5. [source] Initial exploration of tribological performance of novel triazine derivatives in waterLUBRICATION SCIENCE, Issue 4 2009Liping Sheng Abstract Two novel ashless and non-phosphorus triazine derivatives, 2,4,6-tri-[N-hydroxyethyl-amino-methylenesulfanyl]-s-triazine and 2,4,6-tri-[N,N-bishydroxyethyl-amino-methylenesulfanyl]-s-triazine, were synthesised and their structures were analysed through elemental analysis. Their tribological behaviours in water were evaluated with a four-ball machine, and the results indicate that their wear resistance and load-carrying properties were excellent. The chemical features of the worn steel surface were observed and examined by means of inverted metallurgical microscopy and energy dispersive X-ray spectroscopy. The analytical results of typical elements on the worn steel surface demonstrated, during the lubricating process, that the additives reacted with counter-face metal and generated a boundary lubricating and protecting film containing elements of S, N and others, which contributes to improve the tribological properties of the test fluid.
