- Design and synthesis of new imidazo[1,2-a]pyridine and imidazo[1,2-a]pyrazine derivatives with antiproliferative activity against melanoma cells
-
Melanoma is an aggressive form of skin cancer and it is generally associated with poor prognosis in patients with late-stage disease. Due to the increasing occurrence of melanoma, there is a need for the development of novel therapies. A new series of diarylamide and diarylurea derivatives containing imidazo[1,2-a]pyridine or imidazo[1,2-a]pyrazine scaffold was designed and synthesized to investigate their in vitro efficacy against the A375P human melanoma cell line. We found several compounds expressing submicromolar IC50 values against the A375P cells, from which 15d, 17e, 18c, 18h, 18i demonstrated the highest potencies with IC50 below 0.06 μM.

- Identification of a series of compounds with potent antiviral activity for the treatment of enterovirus infections
-
Rhinovirus (genus enterovirus) infections are responsible for many of the severe exacerbations of asthma and chronic obstructive pulmonary disease. Other members of the genus can cause life-threatening acute neurological infections. There is currently no antiviral drug approved for the treatment of such infections. We have identified a series of potent, broad-spectrum antiviral compounds that inhibit the replication of the human rhinovirus, Coxsackie virus, poliovirus, and enterovirus-71. The mechanism of action of the compounds has been established as inhibition of a lipid kinase, PI4KIIIβ. Inhibition of hepatitis C replication in a replicon assay correlated with enterovirus inhibition.
