Additional reflections seemingly leading to a tetragonal fivefold supercell have been observed in a number of melilites. A careful examination of the collected intensity data reveals that this feature is due to the coexistence of two twin domains related by a (120) twin plane. Reflections of the first domain (I) with h(b)(2) + k(b)(2) = 5n overlap those of the second domain (II) when both the f...
The thermolysis of several N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)pyridin-n-amines (where n = 2, 3 and 4) gives a mixture of thiazolopyridine-2-carbonitriles in low to moderate yields. Introduction, by design, of a chlorine substituent at the C2 or C4 position of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)pyridin-3-amine and other selected azines enables a BnEt(3)NI mediated ANRORC style ring t...
Screening identified 2-(3-((4,6-dioxo-2-thioxotetrahydropyrimidin-5(2H)-ylidene)methyl)-2,5-dimethyl-1H-pyrrol-1-yl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile as an MDM2-p53 inhibitor (IC50 = 12.3 μM). MDM2-p53 and MDMX-p53 activity was seen for 5-((1-(4-chlorophenyl)-2,5-diphenyl-1H-pyrrol-3-yl)methylene)-2-thioxodihydropyrimidine-4,6(1H,5H)-dione (MDM2 IC50 = 0.11 μM; MDMX IC50 = 4.2...
The phytotoxic potential of plants and the effect their active components on another plant species is being explored as a alternative to synthetic herbicides for weed control. In current study, we investigated leaves Dregea volubilis (L.f.) Benth. ex Hook.f. against four test [timothy (Phleum pratense L.), barnyard grass (Echinochloa crus-galli (L.) P. Beauv), lettuce (Lactuca sativa alfalfa (M...
The aim of this work is to develop methods synthesis 3-arylaminomethyl-1-(2-oxo-2-arylethyl)-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[4,3-a]azepin-1-ium bromides and aryl-(4-R1-phenyl-5,6,7,8-tetrahydro-2,2a,8a-triazacyclopenta[cd]azulen-1-ylmethyl)-amines study their antimicrobial activity against strains gram-positive gram-negative bacteria as well yeast fungi.

the diuretic activity of methanol extract of oxystelma esculentum aerial parts (meoe) was studied in male wister albino rats at 5h and 24h interval. the animals were divided into 5 groups: control, urea, furosemide and 200mg/kg and 400mg/kg meoe. the extract was administered intraperitoneally (i.p) pretreated and all animals were saline meoe. the urine volume (in ml) and electrolytes excretion ...
