An evolutionary perspective is dominant in many of the most active fields of biological research, such as comparative genomics and evolutionary developmental biology.
Compounds 3g, 6c, 6e, 6h, 9d, 9e, 9h and 9m (Fig. 1) were identified as the most active on the biological assays, and will be studied further.
Proteomics by name is almost 20 years old and has rapidly grown into one of the most active research areas in biological sciences.
We propose that high biological activity of the most active BAT conjugates is a result of their greatly increased intracellular accumulation.
The most active compound on the two biological targets was 27 which exhibited the following IC50: 110 nM for CDK5, 24 nM for DYRK1A and only 1.2 μM for GSK3.
In our series of derivatives a phenyl ring directly linked with the C4 amino function (anilino derivative SI 83), or spaced by a methylene (benzylamino derivative SI 34) or an ethylene (phenylethylamino derivative SI 35) unit afforded the most active compounds, at least for the biological activities tested until now.
The biological results show that the most active compounds possess an antifungal activity comparable or higher than Fluconazole against Candida albicans, non-albicans Candida species, Cryptococcus neoformans and dermathophytes.
Ex vivo biological evaluations indicated that the most active compounds, belonging to series B, displayed a marked vasorelaxant activity on endothelium-intact aortic rings and the trachea.
It is in accordance with the known biological information that the most active EGFR inhibitors like gefitinib drug demonstrate the above characteristics.
Biological evaluation indicated that the most active compound B9, containing 5- 4-hydroxyphenyl -3H-1,2-dithiole-3-thione moiety as H2S donor, had better analgesic activity and displayed more potent cytotoxic effects on the test cell lines than the lead compound CAP.
