Abstract:
Tyrosyl-DNA phosphodiesterase 1 (Tdp1) is a DNA repair enzyme that mends topoisomerase 1-mediated DNA damage. Tdp1 is a current inhibition target for the development of improved anticancer treatments, as its inhibition may enhance the therapeutic effect of topoisomerase 1 poisons. Here, we report a study on the development of a novel class of Tdp1 inhibitors that is based on the octahydro-2H-chromene scaffold. Inhibition and binding assays revealed that these compounds are potent inhibitors of Tdp1, with IC50 and KD values in the low micromolar concentration range. Molecular modelling predicte

Abstract:
Thermal explosions result when local temperature-dependent heat generation exceeds heat loss via conduction. The temperature dependence of the heat source term is directly related to the material’s chemical kinetics, and hence the chemical kinetics has a direct impact on the thermal explosion times of a material. Much success has been gained in past work to accurately model thermal explosions in various explosives using multi-step Arrhenius chemical kinetics models. However, the generation of these kinetics models is time consuming and complex. Therefore, a methodology has been developed that
