In gas phase, collisions that affect the rotational angular momentum lead to the return of the magnetization to its equilibrium (relaxation) in Nuclear Magnetic Resonance (NMR). To the best of our knowledge, the longitudinal relaxation rates R1 = 1/T1 of protons in H2O and HDO have never been measured in gas phase. We report R1 in gas phase in a field of 18.8 T, i.e., at a proton Larmor frequen...

Alternaria porri causing purple blotch disease of onion is a destructive phytopathogen which causes severe loss in productivity. The present study aimed to unravel the antagonistic potential and efficacy volatile organic compounds produced by various Trichoderma spp. against A. through Gas chromatography-mass spectrometry (GCMS) analysis. Ten isolates species were isolated from rhizospheric soi...

Lead derivatives of 2-cyclohexyl-N-[(Z)-(3-methoxyphenyl/3-hydroxyphenyl) methylidene]hydrazinecarbothioamides 1-18 were synthesized, characterized and evaluated in vitro against HER-2 overexpressed breast cancer cell line SKBr-3. All the compounds showed activity against HER-2 overexpressed SKBr-3 cells with IC50 = 17.44 ± 0.01 µM to 53.29 ± 0.33 µM. (2Z)-2-(3-Hydroxybenzylidene)-N-(3-methoxyp...

During the investigation of ester derivatives (juvenogens, biochemically activated insect hormonogenic compounds) of biologically active alcohols with potential application in insect pest control, a need for availability of all existing stereoisomers of ethyl N-{2-[4-(2-butanoyloxycyclohexyl)methyl]phenoxy}ethyl carbamate occurred. They were synthesized from their chiral precursors, the corresp...

Background and Objective: Regarding the prevalence of epilepsy in human society and with respect to insufficiency of usual treatments, new strategies and methods for medical treatment of epileptic patients are necessary. As NMDA receptor antagonists are the most prominent anti-epileptic drugs, in the present study, we synthesized and investigated anti-epileptic effect of a new piperidine deriva...
