7-Chloro-5-(2-ethoxyphenyl)-1-methyl-3-propyl-2,6-dihydro-1H-pyrazolo[4,3-d]pyrimidine
In the title compound, C(17)H(21)ClN(4)O, the benzene ring is oriented at dihedral angles of 1.59 (3) and 1.27 (3)° with respect to the pyrimidine and pyrazole rings, while the dihedral angle between the pyrimidine and pyrazole rings is 0.83 (3)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a planar (r.m.s. deviation 0.004 Å) six-membered ring.

متن کاملThree-dimensional quantitative structure activity relationship approach series of 3-Bromo-4-(1-H-3-Indolyl)-2, 5-Dihydro-1H-2, 5- Pyrroledione as antibacterial agents
The use of quantitative structure–activity relationships, since its advent, has becomeincreasingly helpful in understanding many aspects of biochemical interactions in drug research.This approach was utilized to explain the relationship of structure with biological activity ofantibacterial. For the development of new fungicides against, the quantitative structural–activityrelationship (QSAR) an...
