N1,N1-Dimethyl-N3-(3-(trifluoromethyl)phenethyl)propane-1,3-diamine, a new lead for the treatment of human African trypanosomiasis
摘要:
The natural product, convolutamine I (1), has anti-trypanosomal activity however it has a high molecular weight of 473 due to a presence of 3 bromine atoms. The synthesis of the natural product convolutamine I (1) together with its analogues are presented. A SAR study against Trypanosoma brucei brucei led to compounds with improved physico-chemical properties: lower molecular weight and lower log P while maintaining potency (with a slight 2-fold improvement).

The present invention relates to a three component composition consisting of a polyol component (A) comprising at least two polyols, one with high, one with low molecular weight and water, a polyisocyanate component (B) comprising a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, or a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one further polyol with an amount of between 1% and 30% based on the weight of said polyisocyanate component (B), wherein said MDI product and said polyol have reacted at least partially, and a powder component (C) comprising at least one hydraulic binder, preferably cement and/or calcined paper sludge, preferably a calcium compound selected from calcium hydroxide and/or calcium oxide, and optionally one or more aggregates. The composition contains 2-(Dimethylamino)ethanol, whereby the molar ratio of the 2-(Dimethylamino)ethanol to the OH-groups of the polyol P1 a is between 0.0008 and 0.013 and the weight ratio of components (A+B) to component (C) ((A+B)/(C)) is in the range of 2 : 1.5 to 2 : 3.5, wherein components (A+B) represents the combined weight of component (A) and component (B). The inventive three component composition can be used as primer layer or scratch coat for flooring, especially industrial flooring, applications. The inventive three component composition can provide a waterproofing layer on substrates, especially concrete substrates, that enables good adhesion and proper performance of the flooring systems applied onto them. The inventive three component composition exhibits over a broad temperature range from 5 - 35°C good characteristics as to workability and open time.
