The invention provides compositions and methods for the treatment or prevention of pain. The invention provides constructs whereby hydrolysis of the construct by a specified gastrointestinal enzyme directly, or indirectly, releases an opioid when taken orally as prescribed. The gastrointestinal enzyme mediated release of opioid from constructs of the invention is designed to be attenuated in vivo via a saturation or inhibition mechanism when overdoses are ingested. The invention further provides constructs that are highly resistant to oral overdose, chemical tampering, and abuse via non-oral routes of administration.
Inclusion compounds of cationic, anionic, and neutral p-substituted derivatives of tert-butylbenzene complexed in beta-cyclodextrin and its ionic 6-mono and 6-hepta derivatives were systematically investigated by isothermal titration calorimetry (ITC). All inclusion compounds showed 1:1 stoichiometry with binding constants ranging from 10 to 3 x 10(6) M(-1). The binding free energies could be subdivided
通过等温滴定量热法(ITC)系统地研究了络合在β-环糊精中的叔丁基苯的阳离子,阴离子和中性对位取代衍生物的包合物。所有包含化合物均显示1:1的化学计量比,结合常数范围为10到3 x 10(6)M(-1)。结合自由能可细分为非极性和静电贡献。静电相互作用可以根据库仑定律通过考虑主体和客体的质子化程度,主体内客体的方向以及Debye-Huckel-Onsager理论描述的离子屏蔽来定量描述。客体在环糊精腔内的取向通过ROESY NMR光谱法确定。

A method for the treatment and/or reduction of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) is disclosed. The method uses active amino-aryl-benzamide compounds and methods for the preparation thereof.
Guanylation proceeded efficiently upon treatment of the various amines with cyanamide in the presence of catalytic amounts of scandium(III) triflate under mild conditions. The method did not require the guanylation reagents to be preactivated, and the reaction proceeded efficiently in water. The method, therefore, has practical utility for substrates that dissolve only in aqueous solutions, for example, peptides or pharmacologically important compounds.
