Aminothiazolylacetamidocephalosporins having 1-carboxyethoxyimino groups were synthesized and found to have excellent antibacterial activities including anti-pseudomonal activity and low toxicities. Among these cephalosporins, ME1228 having (S)-1-carboxyethoxyimino substituent and being combined with an (N-ethyl-4-pyridinio)thiomethyl group at C-3 showed marked therapeutic effects against syste...

A series of known and newly synthesized pyrido-1,2-thiazine derivatives of type 3-6 were evaluated against strains of Mycobacterium fortuitum (PCM 672) and Staphylococcus aureus (PCM 2602) The pilot experiments showed that most of the compounds in initial in vitro microbiological evaluation were not efficient antibacterial agents, but unexpectedly promoted replication of the microorganisms in t...

Objective The objective of this study is to evaluate a meticulous pharmacognostic cram is to supplement constructive information with regard to its identification, characterization, and standardization of endemic and endangered medicinal climber Cayratia pedata var. glabra and also screening the antibacterial activity of this climber. Materials and Methods The morphological characters of stud...

A new antibiotic designated MM 14201 has been detected in a culture of Streptomyces sp. NCIB 11813. Methods for the production and purification of MM 14201 are described. Biological evaluation has shown it has broad spectrum antibacterial activity being most effective against Serratia and Pseudomonas sp. Structural studies are reported which have demonstrated MM 14201 is a new epoxyquinone deri...

BACKGROUND Deodorant products prevent the growth and activity of the degrading apocrine gland bacteria living in the armpit. Common antibacterial agents in the market like triclosan and aluminum salts, in spite of their suitable antibacterial effects, increase the risk of Alzheimer's disease, breast and prostate cancers or induce contact dermatitis. Therefore, plant extracts possessing antibact...

OBJECTIVE Quinolone moiety is an important class of nitrogen containing heterocycles widely used as key building blocks for medicinal agents. It exhibits a wide spectrum of pharmacophores and has bactericidal, antiviral, antimalarial, and anticancer activities. In view of the reported antimicrobial activity of various fluoroquinolones, the importance of the C-7 substituents is that they exhibit...

The customary methods of evaluation of chemical disinfectants concern the question of the germicidal performance under specified conditions of these products compared with that of a reference material. As a rule, the fundamental answer is sought to this query: When used in the recommended dilution, will a given disinfectant kill the test-organism wvithin the specified short period of time? From...

INTRODUCTION Coumarins exert many biological effects in humans, animals, and plants, which make the evaluation of their biological activities and study of their role in ethnomedicine highly valued. OBJECTIVES Here, we selected seven plants which have ethnopharmacological use as antimicrobial in Iraq and the aims were to quantify the two structural isomers bergapten and methoxsalen in their se...
