In the title compound, C(18)H(17)BrN(2)O(2), which is a potential -human immunodeficiency virus type 1 (HIV-1) non-nucleoside reverse transcriptase inhibitor, the pyrrolidine ring exhibits an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds [N⋯O = 2.861 (3) Å] link the mol-ecules into centrosymmetric dimers.

In the title compound, C(17)H(13)N(3)O(2), the pyrazine ring is oriented at 1.65 (11) and 88.33 (17)° with respect to the benzene rings. The benzene rings are nearly perpendicular to each other [dihedral angle 87.14 (17)°]. In the crystal, a weak C-H⋯N hydrogen bond occurs.

a new facile route for synthesis of 3- (aryl) -8, 9- di (alkyl) thieno [3,2-e] [1,2,4] triazolo pyrimidines derivative from the same starting material, 2- amino - 4,5 -di (alkyl) thiophene-3- carboxamide, has been developed through heterocyclization of the corresponding arylidene-hydrazino -5,6 -di (alkyl) thieno [2,3-d] pyrimidine under refluxing condition with acetic anhydride followed by air...

In the title mol-ecule, C(7)H(8)ClN(3)O, the pyrazine and amide groups are almost co-planar [N-C-C-N torsion angle = -2.4 (2) °], a conformation stabilized by an intra-molecular N-H⋯N hydrogen bond. The chloro-ethyl group lies out of the plane [N-C-C-Cl = -65.06 (17) °]. In the crystal, the presence of N-H⋯N hydrogen bonds leads to the formation of a C(6) supra-molecular chain along the b axis....

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. ...
