It has been reported that DEX, a common sedative used in the clinic, promotes the proliferation and invasion of multiple tumors. Here, we investigated the effects of DEX on hepatoma cells. The molecular formula of DEX is shown in Fig.3a. We found that various concentrations of DEX (0.01–...
Deep learning has acquired considerable momentum over the past couple of years in the domain of de novo drug design. Here, we propose a simple approach to the task of focused molecular generation for drug design purposes by constructing a conditional rec
Suitable linear polyesters are in particular those which are obtained by polycondensation of terephthalic acid or an ester thereof with a glycol of the formula HO--(CH2)n--OH, in which n is an integer from 2 to 10, or with 1,4-di(hydroxymethyl)cyclohexane, or by polycondensation of a gl...
