Stachys lavandulifolia Vahl is an herbaceous wild plant native to Iran which is traditionally used in Iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. Our previous study on ethyl acetate extract of S. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...

A series of 4-(substituted)-N-(guanidinyl)benzenesulfonamides bearing biologically active pyrazole, pyrimidine and pyridine moieties were prepared and evaluated for their anticancer activity against human tumor breast cell line (MCF7). These sulfonamides showed promising activity with IC50 values ranging from 49.5 to 70.2 μM. The structure-activity relationship of the synthesized compounds was ...

Two nitrogen atoms containing heterocyclic compounds or diazines, pyridazines, pyrimidines and piperazines are important structural feature of many biologically active compounds and show diverse pharmacological properties. These diazines hold considerable interest in the preparation of organic intermediates and physiologically active compounds. Diazines focus our attention because of their easy...

Pyrazole is associated with wide range of biological properties. These ring systems are incorporated into drugs used for AIDS, cancer, anti-viral treatment etc. Pyrazole derivatives are well established in the literature as important biologically active compounds. They have a long history of application in agrochemicals and pharmaceutical industry as herbicides and active pharmaceuticals. Pyraz...

Biologically active heterocyclic compounds comprise of largest & manifold family organic compounds. These include Quinolines, Quinazolines, Aminoquinolines, etc and their derivatives. They exhibit multi-faceted biological properties like analgesic, anti-inflammatory, anticonvulsant, antibacterial, antifungal, antidepressant, anticancer, antitubercular &antihistaminic. are considered to ...

Retention behavior of molecules mostly depends on their chemical structure. Retention data of biologically active molecules could be an indirect relationship between their structure and biological or pharmacological activity, since the molecular structure affects their behavior in all pharmacokinetic stages. In the present paper, retention parameters (RM0) of biologically active 1,2-O-isopropyl...
