Oxadiazole derivatives as a novel class of antimitotic agents: Synthesis, inhibition of tubulin polymerization, and activity in tumor cell lines
摘要:
Oxadiazole derivatives were synthesized and evaluated for their ability to inhibit tubulin polymerization and to cause mitotic arrest in tumor cells. The most potent compounds inhibited tubulin polymerization at concentrations below 1 mu M. Lead analogs caused mitotic arrest of A431 human epidermoid cells and cells derived from multi-drug resistant tumors (10, EC50 = 7.8 nM). Competition for the colchicine binding site and pharmacokinetic properties of selected potent compounds were also investigated and are reported herein, along with structure-activity relationships for this novel series of antimitotic agents.

Disclosed are compounds able to modulate the activity of the GPR17 receptor in a highly specific way, which are useful in the treatment and diagnosis of diseases or dysfunctions involving the activation of said receptor. In particular, the compounds according to the invention can be used for neuroprotective and/or reparatory purposes, in cerebral, cardiac and renal ischaemia, in cerebral trauma, in chronic neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), and in demyelinating diseases such as multiple sclerosis.

In the present study, we attempted to develop a novel class of compounds active against Pseudomonasaeruginosa (Pa) by exploring the pharmaceutically well exploited enzyme targets. Since, lack of Pa gyrase B crystal structures, Thermus thermophilus gyrase B in complex with novobiocin (1KIJ) was used as template to generate model structure by performing homology modeling. Further the best model was
