A series of hydroxamic acids (aceto-, propiono-, benzo-, and p-nitrobenzo-) and seven derivatives of these were examined for biological activity using Salmonella typhimurium. Acylation to yield O-acetyl and O-benzoyl derivatives markedly enhanced toxic properties and was necessary for mutagenic activity for all but p-nitrobenzohydroxamic acid. The dose necessary to produce a minimum significant...

Nucleotide-binding sites on the chloroplast coupling factor 1 (CF1) have been probed using two photoreactive ADP analogs: 2-azido-ADP (2-N3-ADP) and 2',3'-O-(4-benzoyl)benzoyl-ADP (Bz-ADP). Photolabeling of the isolated CF1 with 2-N3-ADP results in incorporation of the analog exclusively into the beta-subunit of the enzyme. The location of the nucleotide-binding site(s) within the beta-subunit ...

Phenethyl isothiocyanate (PEITC), 3-phenylpropyl isothiocyanate (PPITC), 4-phenylbutyl isothiocyanate (PBITC), and the newly synthesized 5-phenylpentyl isothiocyanate (PPeITC), 6-phenylhexyl isothiocyanate (PHITC), and 4-(3-pyridyl)butyl isothiocyanate (PyBITC) were tested for their abilities to inhibit tumorigenicity and DNA methylation induced by the tobacco-specific nitrosamine 4-(methylnitr...

      Benzoyl peroxide (BPO) is a first-line topical treatment in acne vulgaris, and it is superior to antibiotics, because the bacteria do not develop resistance to it. Skin irritation is a common side effect, and it has been shown that controlled release of BPO from a delivery system to the skin could reduce the side effects while reducing percutaneous absorption. Therefore, the purpose of t...

N-benzoyl-N'-phenylthiourea (BFTU) compound is similar to amprenavir derivatives in the urea compound, chloroquine -NH group, and benzene ring, which a potent antiviral. This study evaluated effect of lipophilic, electronic, steric parameters BFTU on antiviral activity Covid-19. In silico docking using Autodock 4.2 confirm pkCSM webserver predict bioavailability toxicity. The SARS-CoV-2 recepto...
