متن کاملSynthesis, Characterization and Antibacterial Activity Studies of Some N-Acyl-N'-aryl Thiourea Derivatives
Some N¬-acyl-N'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. The structures of synthesized compounds have been characterized by IR, 1HNMR spectral studies. The synthesized compounds 5(a-f) have been screened for antibacterial activity. The effect of the structure of the investigated compounds on the antibacterial activ...
متن کاملTime-Dependent Behavior of Insoluble Monomolecular Films: Fatty Acids and Some Derivatives
Saturated fatty acids ranging from 15 to 20 carbons in Mkyl chain length and some stearic acid derivatives were spread as insoluble monomoleeular films and compressed at a constant velocity. As these surface films assume close packing, they exhibit a loss in surface pressure when held at constant area below an apparent collapse pressure which is not due to dissolution into the subphase solution...
متن کاملAssessment of Fatty Acids and Phenolic Content of some Citrullus colocynthis Accessions seeds from Iran.
Bitter melon (Colocynth) is a species of herbs, annual medicinal plant of family Cucurbitaceae which are mainly grown in warm regions of Iran. Fatty acids of the seeds of this plant are considered as important materials, medicinally. In this study, essential fatty acids of seed collected from nine different regions of Iran were evaluated. The composition of fatty acids such as oleic, linoleic, ...
