Aminoguanidine hydrochloride is a white to off-white crystalline compound that has been identified as an inhibitor of animal nitric oxide (NO)-synthase. Its crystal structure, investigated through Fourier and least squares methods, reveals a monoclinic form with a planar guanidine part of the aminoguanidinium ion. Aminoguanidine is known to be equipotent to L-NMMA and L-NNA as an inhibitor of iNOS, with IC50 values of 5.4 and 160 μM for mouse iNOS and rat nNOS, respectively. It also inhibits the induction of iNOS protein expression by endotoxin in rat macrophages.

Check Digit Verification of cas no

The CAS Registry Mumber 1937-19-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,3 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1937-19:
(6*1)+(5*9)+(4*3)+(3*7)+(2*1)+(1*9)=95
95 % 10 = 5
So 1937-19-5 is a valid CAS Registry Number.

Green Energetic Nitrogen-Rich Salts of 1,1′-Dinitramino-5,5′-bistetrazolate

He, Piao,Wu, Le,Wu, Jinting,Wang, Qianyou,Li, Zhimin,Gozin, Michael,Zhang, Jianguo

supporting information, p. 11159 - 11168 (2017/08/22)

A series of nitrogen-rich energetic salts of 1,1′-dinitramino-5,5′-bistetrazolate (DNABT) guanidinium (1), aminoguanidinium (2), diaminoguanidinium (3), triaminoguanidinium (4), diaminouronium (5), 3,4-diamino-1,2,4-triazolium (6), and ethylenediammonium (7) was synthesized by a metathesis strategy and characterized by elemental analysis, mass spectrometry, and IR spectroscopy as well as single-crystal X-ray diffraction and differential scanning calorimetry (DSC). The natural bond orbitals (NBOs) and electrostatic potentials (ESPs) were further computed for a better understanding of the structures of the DNABT molecule. The heats of formation were calculated based on the Born–Haber energy cycle. The detonation parameters were evaluated by using the EXPLO5 program, and the sensitivities were measured according to BAM standers. These new salts exhibit highly positive heats of formation (407.0–1377.9 kJ mol?1) and good thermal stabilities (180–211 °C). Most of these compounds possess detonation velocities comparable to RDX and acceptable detonation pressures. The high volumes of explosion gases of the salts 3 and 4 (921 and 933 L kg?1, respectively) further support their power as explosives. The enhancing performances, the fact of being free of metals, and the more moderate sensitivities than K2DNABT, suggest that the salts 4 (D=8851 m s?1, P=29.0 GPa), 5 (D=9053 m s?1, P=32.3 GPa), and 6 (D=8835 m s?1, P=30.2 GPa) might be potential environmentally friendly energetic materials.

Thermodynamic and kinetic aspects of a single-reactor synthesis of 5-amino-3-methyl-1,2,4-triazole hydrochloride from aminoguanidine and acetic acid

Tarasova,Chernyshev,Chernysheva,Abagyan

experimental part, p. 400 - 406 (2011/08/04)

Fundamental thermodynamic and kinetic aspects of the reaction in which acetic acid guanyl hydrazide is formed from aminoguanidine and acetic acid in aqueous solutions at pH 0.6-1.5 and the kinetics of cyclization of acetic acid guanyl hydrazide hydrochloride to 5-amino-3-methyl-1,2,4-triazole hydrochloride in a melt were studied. Methods for synthesis of acetic acid guanyl hydrazide hydrochlorides and 5-amino-3-methyl-1,2,4-triazole hydrochloride were developed.

Mechanism of general acid-base catalysis in transesterification of an RNA model phosphodiester studied with strongly basic catalysts

Corona-Martinez, David O.,Taran, Olga,Yatsimirsky, Anatoly K.

supporting information; body text, p. 873 - 880 (2010/06/20)

Using 80% vol aqueous DMSO as the reaction medium for transesterification of an RNA model substrate 2-hydroxypropyl 4-nitrophenyl phosphate allows one to observe catalysis in buffer mixtures composed of highly basic components such as guanidines, amidines or alkylamines, which provide up to 103-fold accelerations over the background reaction in the 0.01-0.1 M concentration range. The rate law kobs = k1[B] + k2[B] [BH+] was established indicating contributions from both simple general base catalysis and the reaction involving concerted action of neutral (B) and protonated (BH+) forms of the buffer. The catalytic efficiency of guanidinium and amidinium cations is 10 times larger than that of more acidic ammonium cations. Rate constants k1 and k2 obey the Bronsted equations with the slopes 0.77 and 0.69 respectively. Proton inventory for k2 (B = guanidine) in D2O/H 2O mixtures gives two fractionation factors φ1 = 0.48 and φ2 = 1.26 for normal and inverse isotope effects respectively. The former results from the proton transfer to B and the latter from the binding of guanidinium cation to the phosphate group as follows from observation of an inverse solvent isotope effect for the binding of guanidinium and amidinium cations to a phosphodiester anion. The results of kinetic studies together with analysis of transition state stabilization free energies for guanidinium and amidinium cations show that the protonated buffer component acts via electrostatic transition state stabilization rather than proton transfer, which may be possible for a guanidinium assisted hydroxide catalyzed reaction.

supporting information; experimental part, p. 8168 - 8172 (2009/12/07)

Synthesis and characterization of (R)-Nα-(2,2- diphenylacetyl)-N-(4-hydroxybenzyl)-Nω-([2,3- 3H]-propanoyl)-argininamide ([3H]-UR-MK114), an easily accessible tritium-labeled NPY Y1 receptor (Y1R) antagonist (KB: 0.8 nM, calcium assay, HEL cells) derived from the (R)-argininamide BIBP 3226, is reported.

, p. 7897 - 7901 (2007/10/03)

The design and synthesis of antitumor imidazothiazole guanylhydrazones are reported. The compounds were submitted to NCI for testing. All but one were more active than methyl-GAG. A few compounds were selected for further studies in search of a possible mechanism of action. The results from these studies and a final search with the NCI COMPARE algorithm suggest that the guanylhydrazones described in this paper are acting through a novel mechanism of action.
