Diaryl hydrazones, possessing similar structure to the popular red wine antioxidant resveratrol, have been previously identified as multitarget compounds interfering with several processes associated with the pathogenesis of Alzheimer’s disease (AD). These compounds exhibited particularly strong inhibition of the amyloid beta (A) peptide self-assembly, including blocking the formation of fibrils and oligomers, species that are widely accepted to be neurotoxic. The molecules were also powerful free radical scavengers and thus have a potential to defend against oxidative stress.

In order to learn more about the mode of action of the compounds, theoretical and experimental studies have been carried out ...

Soil-transmitted helminths (STHs), most notably, hookworms, whipworms, and Ascaris, are nematodes that infect more than 1.5 billion of the poorest people and are amongst the leading causes of morbidity worldwide. Only two classes of de-worming drugs (anthelmintics) are available for treatment, and only one is commonly used in mass drug administrations. New anthelmintics are urgently needed to overcome emerging resistance and to produce higher cure rates. Crystal (Cry) proteins, in particular Cry5B, made by Bacillus thuringiensis (Bt) are promising new candidates. Cry5B has excellent anthelmintic properties against many free-living and parasitic nematodes, including in vivo efficacy against multiple STH ...


Structural Activity Relationship Study On Dual Plk1 /Brd4 Inhibitor, Bi- 2536, Hailemichael Yosief, Shuai Liu, Dennis L. Buckley, Justin M. Roberts, Alex M. Muthengi, Francesca M. Corsini, James E. Bradner, Wei Zhang May 2016

Polo-like kinase 1 (PLK1) and BRD4 are two different therapeutic targets in cancer drug discovery. Recently it has been reported that PLK1 inhibitor, BI-2536, is also a potent inhibitor of BRD4. The simultaneous inhibition of PLK1 and BRD4 by a single drug molecule is interesting because this could lead to the development of effective therapeutic strategy for different types of disease conditions in which PLK1 and BRD4 are implicated. Structural activity relationship studies has been carried out on BI-2536 to generate analogs with enhanced dual inhibitory activity against BRD4 and PLK1 as well as to render the molecule selective to ...


Terpenes As ‘Resistance-Busting” Anthelmintic Drug, Zeynep Mirza, David Koch, Thanh-Thanh Nguyen, Yan Hu, Raffi V. Aroian, Gary R. Ostroff May 2016

There is an urgent need for new therapies for parasitic helminthic diseases affecting 1.5-2 billion people worldwide due to the threat of wide-spread resistance development to existing treatments and due to problems of incomplete efficacies.

Terpenes are plant secondary metabolites and major essential oil constituents. Historically, the terpene thymol was successfully used to cure hookworm infections in the 1900’s. Although effective, large doses were needed and thymol treatment had significant side effects. Because free terpenes are absorbed in the stomach, less than 10% of oral terpenes entered the site where the parasites live. To overcome these problems we ...
