In the present study, five new derivatives (GG4 to GG8) of benzothiazoles were synthesized and evaluated against Staphylococcus aureus (MTCC 737), Pseudomonas aeruginosa (MTCC 424), Escherichia coli (MTCC 1687), and yeast-like fungi Candida tropicalis. p-Toluidine on treatment with ammonium thiocynate formed 2-benzothiazolamines (II), which on reaction with hydrazine hydrate formed a hydrazino ...
New series of 2-hydrazino-7,8-dihydro-6H-cyclopenta[5,6] pyrido[2,3-d]pyrimidines and its 1,7,8,9-tetrahydrocyclopenta[5,6]pyrido[2,3-d][1,2,4]triazolo[4,3-a]pyrimidine, 1,7,8,9-tetrahydrocyclopenta[5,6]pyrido[2,3-d][1,2,3,4]tetrazolo[4,5-a]pyrimidine, 8,9-dihydro-7H-cyclopenta[5,6]pyrido[2,3-d]imidazolo[1,2-a]pyrimidine, 2-(pyrazol-1-yl)-7,8-dihydro-6H-cyclopenta[5,6]pyrido[2,3-d]pyrimidine de...
Abstract α-Boryl-α-hydrazinoacetic acid is a highly functionalized boron-containing building block that can be easily accessed from readily available α-borylacetaldehyde. The hydrazine motif converted into variety of α-borylated azoles and diazines in straightforward protocol. Furthermore, the carboxy group derivatized to afford novel organoboron compounds should find applications various cross...
TiTHE PHYSIOLOGIC and pathologic consequences of magnesium deficit or excess iii animals, and the important role of magnesium as a cofactor in many enzyme systems have been well recognized. However, knowledge concerning the role of magnesium in human disease has lagged behind that of sodium and potassium. This has been, in part, due to the fact that methods for the determination of magnesium in...
Autotaxin (ATX), a lysophospholipase D, plays an important role in cancer invasion, metastasis, tumor progression, tumorigenesis, neuropathic pain, fibrotic diseases, cholestatic pruritus, lymphocyte homing, and thrombotic diseases by producing the lipid mediator lysophosphatidic acid (LPA). A high-throughput screen of ATX inhibition using the lysophosphatidylcholine-like substrate fluorogenic ...
Stimulation and inhibition tests are proposed for evaluating prolactin secretion. Thyrotropin-releasing hormone (TRH) stimulates the release of prolactin from the pituitary. Chlorpromazine acts presumably at the hypothalamic level to increase prolactin secretion. L-Dopa (D,L-alpha-hydrazino-alpha-methyl-beta-[3,4-di-hydroxyphenyl]) has the opposite effect; it inhibits prolactin secretion and ma...
The first electrophilic α-amination reaction of labdane-type diterpene (−)-(5S,9S,10S,13S)-labd-7-en-15-oic acid and (+)-(5S,8R,9R,10S,13R)-8-hydroxylabdan-15-oic acid, isolated from aerial parts Ageratina jocotepecana is presented. In the presence dibenzylazodicarboxylate proline followed by an in situ reduction, corresponding hydrazino alcohols were obtained. It demonstrated that moiety had n...
1-(2,4-Dichlorophenyl)-3-(4-fluorophenyl)propen-1-one (1) was prepared and reacted with an active methylene compound (ethyl cyanoacetate) in the presence of ammonium acetate to give the corresponding cyanopyridone 2. Compound 2 reacted with hydrazine hydrate, malononitrile, ethyl bromoacetate and phosphorous oxychloride to afford compounds 4 and 7-11, respectively. The 2-chloropyridine derivati...
