Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with the enzyme ceramide galactosyltransferase (CGT), such as, for example, lysosomal storage diseases. Examples of lysosomal storage diseases include, for example, Krabbe disease and Metachromatic Leukodystrophy.
ABATRACT A direct approach to N,N′-disubstituted urea/thiourea from the self-condensation reactions of isothiocyanates in water has been developed. This access tolerated a wide range of functional groups on the aromatic ring, providing a practical and environment-friendly process to N,N′-disubstituted urea/thiourea in moderate to excellent yields from safe and easily available starting materials.

ABATRACT 已经开发了一种从异硫氰酸酯在水中的自缩合反应直接得到N , N '-二取代脲/硫脲的方法。这种访问容忍了芳环上的多种官能团,为N , N '-二取代脲/硫脲提供了一种实用且环境友好的工艺,从安全且易于获得的起始材料以中等至优异的产率。还提出了尿素脱硫自缩合反应的合理机理,并借助中间体研究的 ESI 质谱分析证明了二叔丁基过氧化物 (DTBP) 和铜催化剂在本策略中的作用。

Ni-catalyzed oxidative double isocyanide insertion to thioureas under air conditions, in which thioureas play three roles as a substrate, a ligand, and overcoming isocyanide polymerization. The reaction is featured by employing a low-cost and low loading Ni(acac)2 catalyst, without any additives, and high atom economy. This is the first example to directly apply a Ni(II) catalyst in oxidative double isocyanide

Organophosphorus (OP) chemicalwarfare agents (CWAs) represent an ongoing threat but the understandable widespread prohibition of their use places limitations on the development of technologies to counter the effects of any OP CWA release. Herein, we describe new, accessible methods for the identification of appropriate molecular simulants to mimic the hydrogen bond accepting capacity of the PO moiety

Square peg in a round ball: Squaramides are shown to be potenttransmembraneaniontransporters for both chloride and bicarbonate, performing better than the thiourea and urea analogues. Studies into the nature of this transport point to a mobile carrier mechanism, where the squaramide delivers the anion cargo across the lipid bilayer (see scheme, green sphere=anion). These drug‐like molecules provide
