In the present study, we have synthesized chalcone and semicarbazide-linked chalonyl derivatives and the titled compounds confirmed by MS, IR, and 1H NMR techniques. The anticonvulsant activity was determined by maximal electroshock (MES) induced seizure method. A majority of the compounds exhibited significant anticonvulsant activity after intraperitoneal administration. The results show the importance
在本研究中,我们合成了查尔酮和氨基脲连接的查洛尔基衍生物,并通过MS,IR和1 H NMR技术确认了标题化合物。通过最大电击(MES)诱发癫痫发作方法确定抗惊厥活性。腹膜内给药后,大多数化合物表现出显着的抗惊厥活性。结果表明氢键对活性的重要性。在本研究中,5e,5h,5i,6e,6h和6i成为最活跃的分子,显示出明显的抗惊厥活性。
Plasmin Regulation through Allosteric, Sulfated, Small Molecules
matrix remodeling. Heparin, a natural polydisperse sulfatedglycosaminoglycan, is known to allostericallymodulate plasmin activity. No smallallosteric inhibitor of plasmin has been discovered to date. We screened an in-house library of 55 sulfated, smallglycosaminoglycanmimetics based on nine distinct scaffolds and varying number and positions of sulfate groups to discover several promising hits.

having broadspectrum activity. On the bases of work done in this area we have applied hybridization of pharmacophore strategy of drug design and developed a new pharmacophore. We have also designed a scheme for synthesizing such pharmacophore and performed their pharmacological screening for the protection of seizures, behavioral study and CNS activity. The compound 1-[1-(2,4-dihydroxyphenyl)-3-(2-h

A set of isoflavononid and flavonoid analogs was prepared and evaluated for estrogen receptor α (ERα) and ERβ transactivation and anti-neuroinflammatory activities. Structure–activity relationship (SAR) study of naturally occurring phytoestrogens, their metabolites, and related isoflavone analogs revealed the importance of the C-ring of isoflavonoids for ER activity and selectivity. Docking study suggested putative binding modes of daidzein 2 and dehydroequol 8 in the active site of ERα and ERβ, and provided an understanding of the promising activity and selectivity of dehydroequol 8. Among the tested compounds, equol 7 and dehydroequol 8 were the most potent ERα/β agonists with ERβ selectivity and neuroprotective activity. This study provides knowledge on the SAR of isoflavonoids for further development of potent and selective ER agonists with neuroprotective potential.
