The title compound, C(10)H(10)N(2)O(2)·H(2)O, is dimerized by inversion-related inter-molecular N-H⋯O hydrogen bonding. There is an intra-molecular N-H⋯O bond, resulting in a six-membered ring. Each dimer inter-acts with other dimers through hydrogen bonding with water mol-ecules. The water mol-ecules are linked to each other in a stair-like chain, thus generating two-dimensional polymeric stri...

n-(7-chloro-1-methyl-2-oxo-5-phenyl-2,3-dihydro-1h-benzo[e][1,4]diazepin-3-yl)thiophene-2 carboxamide-[14c-carboxy] was prepared as part of a 6-step sequence from thiophene-2-carbonitrile -[cyano-14c] as a keysynthetic intermediate which has been synthesized from 2-iodothiophene and zinc [14c]-cyanide in thepresence of tetrakis (triphenylphosphine) palladium.

Built upon the catalytic mechanism-based pan-SIRT1/2/3 inhibitory warhead L-2-amino-7-carboxamidoheptanoic acid (L-ACAH, a close structural analog of N(ε)-acetyl-lysine) that our laboratory discovered recently, in the current study, its carboxamide NH2-ethylated analog was found to be a ∼2.4-6.6-fold stronger SIRT1/2/3 inhibitory warhead than L-ACAH. Carboxamide NH2-dodecylated and carboxymethy...

Isothiazolopyridines, pyridothiazines and pyridothiazepines are important compounds that possess valuable biological activities. This paper reports on the synthesis of these compounds using both conventional chemical methods and modern microwave techniques. 3-Bromo-6-hydroxy-4-methyl-2-thioxo-2,3-dihydropyridine-3-carboxamide, 5-arylazo-6-hydroxy-4-methyl-2-thioxo-1,2-dihydropyridine-3-carboxam...

The title complex, [ZnBr(2)(C(5)H(5)N(3)O)(2)], shows crystallographic mirror symmetry with the Zn atom and the two bromine ligands located on the mirror plane. The Zn atom is four-coordinated in a distorted tetra-hedral fashion by two N atoms from two pyrazine-2-carboxamide ligands and two Br atoms. Only one of the amino H atoms is involved in an N-H⋯O hydrogen bond. The crystal packing is fur...

In the title compound, C(19)H(15)NO(2), the mol-ecule adopts a syn configuration with the naphthalene and N-phenyl-formamide units located on the same side of the ep-oxy ring. The ep-oxy ring makes dihedral angles of 58.73 (9) and 65.18 (9)°, respectively, with the naphthalene ring system and the benzene ring. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonding is present in the crystal structure.

The asymmetric unit of the crystal structure of the title compound, C(16)H(12)N(2)O(2), contains two independent mol-ecules. In each mol-ecule, the two aromatic rings adopt a cis configuration about the central epoxide ring, and are oriented at dihedral angles of 61.5 (5) and 74.4 (5)°with respect to the epoxide ring in one mol-ecule, and 60.1 (5) and 72.1 (5)° in the other one. Inter-molecular...

A series of N-(aminoiminomethyl)-1H-indole carboxamide derivatives were synthesized and their inhibitory potencies against the Na+/H+ exchanger were measured. Variation of the carbonylguanidine group at the 2- to 7-position of the indole ring system showed that a substitution at the 2-position improved the Na+/H+ exchanger inhibitory activity the most in vitro. This led to the synthesis and eva...
