deprotection of phosphate, phosphate, and sulfite esters by silica chloride is described. silica chloride is a mild, selective, and effective reagent for cleavage of benzyl and t-butyl esters of the above compounds.

the present study reports a microwave-assisted method for the synthesis of twelve novel tricyclic 1,4-dihydropyridine derivatives in which dimethyl-substituted cyclohexane and / or tetrahydrothiophene rings are fused to the dhp ring. the structures of the compounds were confirmed by spectral methods and elemental analysis. the potassium channel opening effects of the compounds were determined o...

Batch culture fermentations were used to determine the effects of avoparcin, lasalocid, monensin, narasin, salinomycin, thiopeptin, tylosin, virginiamycin, monensin + tylosin combination, and two new ionophore compounds (RO22-6924/004 and RO21-6447/009) on lactic acid and volatile fatty acid (VFA) production. Ruminal fluid from cattle fed a high alfalfa hay diet was incubated with glucose for 1...

In this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (TNPP) and its zinc porphyrin complex (ZnTNPP) were synthesized in situ using the microwave method and identified by UV-Vis, FT-IR and 1H NMR. The photostability and photodynamic antimicrobial activity (PACT) of these compounds were investigated on Pseudomonas aeruginosa and Bacillus subtilis under visible light irradiation. MIC, MBC an...

The salmon louse, Lepeophtheirus salmonis Krøyer, is the major obstacle facing a sustainable future for farmers of salmonids in the North Atlantic Ocean. Medicinal compounds have been the most utilized tool to prevent salmon lice infestation; however, the active compounds have become less effective or considered environmentally unfriendly in the past years. Novel medicinal compounds are thus hi...

Biofouling causes huge economic loss and a recent global ban on organotin compounds as antifouling agents has increased the need for safe and effective antifouling compounds. Five structurally similar compounds were isolated from the crude extract of a marine Streptomyces strain obtained from deep-sea sediments. Antifouling activities of these five compounds and four other structurally-related ...

background and aims: to evaluate the effect of temperature on wheat streak mosaic virus (wsmv) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using adl-cross (resistant) and marvdasht (susceptible) cultivars. materials and methods: results showed that incubation at 32c changed the gene expression for resistance ...
