Chemistry of bleomycin. XV absolute configuration of beta-amino-beta-(4-amino-6-carboxy-5-methylpyrimidin-2-yl)-propionic acid, an amine component of bleomycin.
(3-Amino-13-(4-amino-6-c a r b o x y5-m e t h y l p y r imidin-2-yl)-propionic acid, designated compound II in the former report,'' is produced by degradation of an amino acid residue containing (3-lactam in the bleomycin molecule .2-4) The absolute configuration of the asymmetric carbon in this part of the bleomycin molecule has been determined by X-ray analysis of IIdiamide hydrobromide.
متن کامل6-Amino-2,5-bis(pivaloylamino)pyrimidin-4(3H)-one dihydrate
The asymmetric unit of the title compound, C(14)H(23)N(5)O(3)·2H(2)O, contains two crystallographically independent 6-amino-2,5-bis-(pivaloylamino)pyrimidin-4(3H)-one mol-ecules (A and B) with similar geometry and four water mol-ecules. In both independent mol-ecules, one of the amide groups is almost coplanar with the pyrimidine ring [dihedral angle of 12.85 (9) in A and 12.30 (10)° in B], whe...
متن کاملMethyl 6-amino-6-oxohexanoate
The title compound, C(7)H(13)NO(3), adopts an approximately planar conformation. The torsion angles in the aliphatic chain between the carbonyl group C atoms range from 172.97 (14) to 179.38 (14)° and the r.m.s. deviation of all non-H atoms is 0.059 Å. The crystal packing is dominated by two strong N-H⋯O hydrogen bonds involving the amide groups and forming R(2) (2)(8) rings and C(4) chains. Ov...
متن کاملMultiband superconductivity in BiS2-based layered compounds.
A mean-field treatment is presented of a square lattice two-orbital-model for [Formula: see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula: see text]) and electron doping x. With the help of ...
متن کامل3-(2-Amino-1,3-thiazol-4-yl)-6-bromo-2H-chromen-2-one
The mol-ecule of the title compound, C(12)H(7)BrN(2)O(2)S, is essentially planar with a maximum deviation of 0.234 (3) Å from the mean plane through all non-H atoms. The dihedral angle between the coumarin ring plane and that of the five-membered thia-zole ring is 12.9 (1)°. In the crystal, strong N-H⋯O, N-H⋯N and weak but highly directional C-H⋯O hydrogen bonds provide the links between the mo...
