Photosystem II Inhibition by 3-Acyl-5-(l-aminoalkylidene)-4-hydroxy- 2 H-pyran-2,6(3 //)-dione Derivatives
3-Acyl-5-( 1 -am inoalkylidene)-4-hydroxy-2 Hpyran-2,6(3 //)-d ione derivatives carrying lipophilic am ino groups were found to be highly potent inhibitors o f photosynthetic electron transport, and bo th the acyl and the am inoalkylidene groups on the pyran ring appeared to be indispensable for high activity. The structural features needed for activity in the 3-acyl-5(l-am inoalkylidene)-4-hyd...
متن کاملTetraaquabis[5-(3-pyridyl)tetrazolido-κN 5]zinc(II) tetrahydrate
The title compound, [Zn(C(6)H(4)N(5))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the hydro-thermal reaction of Zn(CH(3)COO)(2)·2H(2)O with 3-(2H-tetra-zol-5-yl)pyridine. The Zn(II) ion is located on an inversion center and is coordinated by two pyridine N atoms from two 5-(3-pyrid-yl)tetra-zolide ligands and four coordinated water mol-ecules in a slightly distorted octa-hedral geometry. The dihed...
متن کاملSynthesis of 3- Benzylidene, 5-Substituted 3-Benzylidene, 3- Hetarylmethylene and 5-Substituted Hetarylmethylene Derivatives of In- dolin-2-ones
A wide variety of titled compounds, several of which have neuro-protecting properties has been prepared in yields ranging between 70 to 90%. The compounds were identified by 1 HNMR, 13 C NMR, 1D and 2D NOE analysis, and HRMS. An investigation of the effect of certain 5-substitutuents on the E to Z ratios in DMSO-d6 was carried out. The 5nitro and 5-acetyl substituents were not isomerized, where...
متن کاملMicrowave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
متن کامل3-Nitro, 1-Amino Guanidine and 5-Hydrazino-1H-Tetrazole Derivatives as New Energetic Materials
The synthesis of 3-amino-1-nitroguanidine (3-ANQ) and 5-hydrazino tetrazole (5-HT) derivatives as new energetic materials are described. Reaction of 3-ANQ with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-HT. Addition of NaN3 to a mixture of 3-ANQ and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excelle...
