Biosynthesis of Streptomycin. I. Origin of the Guanidine Group.
Although the antibiotic streptomycin was isolated and characterized a number of years ago, little knowledge has accumulated concerning its synthesis by Xtreptonzyces griseus. In I954 Numerof, Gordon, Virgona, and O’Brien (1) administered glycine and acetate labeled in either the carboxyl or the (Y carbon to cultures of X. griseus. A low extent of incorporation of 1% into the streptomycin synthe...
متن کاملBis(dicyclohexylphenylphosphine)silver(I) nitrate
The title compound, [Ag(C(18)H(27)P)(2)]NO(3), is a mononuclear salt species in which the Ag atom is coordinated by two phosphine ligands, forming a cation, with the nitrate as the counter-anion, weakly inter-acting with the Ag atom, resulting in Ag⋯O distances of 2.602 (6) and 2.679 (6) Å. The cationic silver-phosphine complex has a non-linear geometry in which the P-Ag-P angle is 154.662 (19)...

متن کاملGuanidine Structure and Hypoglycemia
By a series of structural changes, Frank, Nothmann, and Wagner (1) developed synthalin, the most powerful hypoglycemic synthetic product known today. The details of their researches are not available. The increased hypoglycemic activity of agmatine over guanidine offered the first clue as to the nature of the groups which were productive of hypoglycemic activity. It may be gathered from the rec...
متن کامل[Total synthesis of marine cyclic guanidine compounds and development of novel guanidine type asymmetric organocatalysts].
Crambescidins and batzelladines, novel marine guanidine alkaloids, have unique pentacyclic and tricyclic guanidine core structures, respectively. They display a considerable array of biological activity and not surprisingly have attracted considerable synthetic interest. The first total synthesis of crambescidin 359 (7) and stereoselective total synthesis of batzelladine D (11) were accomplishe...
