Skin cancer has been reported as a contemporary malignant cancer. Here, anti-cancer effects of sea cucumber extract (SCE) from Holothuria arenicola have been examined on melanoma cells and compared with imidazole carboxamide (Dacarbazine) as a chemotherapy medication against melanoma and Hodgkin's lymphoma. MTT assay and morphological analysis were performed to evaluate cytotoxic effects of H. ...
In the title compound, C(24)H(21)ClN(4)O(2), the pyrazole ring makes dihedral angles of 7.70 (11), 89.17 (11) and 40.68 (11)° with the phenyl, pyridine and ethoxy-phenyl rings, respectively. There are some intra-molecular C-H⋯O and C-H⋯π bonds giving rigidity to the mol-ecule, while weak inter-molecular N-H⋯N and C-H⋯π hydrogen bonds link the mol-ecules into a two-dimensional structure.
the interaction of fe2+ ion with pyrazole was theoretically studied by gussian 03, software at hf/(lanl2dz+6-31g) and hf/ (lanl2dz+6-31g (d)) levels in gas phase and solution. in this study acompartion between optimized structures of pyrazole molecule in aspect of thermodynamicparameters such as enthalpy (h°), gibbs free energy (g°) and entropy (s°) in presence of metallic ion(fe2+), was perfor...

Reactions of 3-bromo-4-phenylisothiazole-5-carboxamide and 3-bromoisothiazole-5-carboxamide with NaNO2 (4 equiv.), in TFA, at ca. 0 °C gave the carboxylic acid products 99% 95% yields, respectively. The two compounds were fully characterized.
interest in agrochemicals and drugs. Aryl group substituted pyrazoles and imidazoles, in particular, have been studied because their biological activities are strongly dependent on their substituents on the pyrazole ring system. 1,5-Diaryl substituted pyrazole (SR141716A, 1), which has a hydrazide group on the 3-position of the pyrazole ring, has recently been synthesized and identified as the ...
In the title compound, C(14)H(15)N(3)O(2), the phenyl-ene ring is disordered over two orientations. As a result, the almost planar pyrazole ring (r.m.s. deviation = 0.004 Å) forms dihedral angles of 59.8 (1) and -61.9 (1)° with the two orientations of the phenyl-ene ring. The dihedral angle between the two orientations is 59.2 (1)°. In the crystal, inversion dimers lined by pairs of N-H⋯O hydro...
Behavioral studies of chronic CB(1) receptor activation may provide a pharmacological approach to understanding efficacy-related differences among CB(1) ligands as well as mechanistic commonalities between cannabinoid and noncannabinoid drugs. In the present studies, the effects of CB(1) agonists [(6aR,10aR)-3-(1-adamantyl)-6,6,9-trimethyl-6a,7,10,10a-tetrahydrobenzo[c]chromen-1-ol (AM411), 9β-...
