The present invention relates to pharmaceutical compositions of various pharmaceutical actives, especially lyophilic and hydrophilic actives containing Diethylene glycol monoethyl ether or other alkyl derivatives thereof as a primary vehicle and/or to pharmaceutical compositions utilizing Diethylene glycol monoethyl ether or other alkyl derivatives thereof as a primary vehicle or as a solvent system in preparation of such pharmaceutical compositions. The pharmaceutical compositions of the present invention are safe, non-toxic, exhibits enhanced physical stability compared to conventional formulations containing such pharmaceutical actives and are suitable for use as injectables for intravenous and intramuscular administration, as well as for use as a preformed solution/liquid for filling in and preparation of capsules, tablets, nasal sprays, gargles, dermal applications, gels, topicals, liquid oral dosage forms and other dosage forms.

structure of the Eis-haloperidol (1) complex, which guided synthesis of 34 analogues. The structure–activity relationship study showed that in addition to haloperidol (1), eight analogues, some of which were smaller than 1, potently inhibited Eis (IC50 ≤ 1 μM). Crystal structures of Eis in complexes with three potent analogues and droperidol (DPD), an antiemetic and antipsychotic, were determined. Three
结核病 (TB) 由结核分枝杆菌( Mtb ) 引起,是一种致命的细菌性疾病。Mtb的耐药菌株使根除结核病成为一项艰巨的任务。Mtb过度表达增强的细胞内存活 (Eis) 蛋白赋予了对二线抗生素卡那霉素 (KAN) 的抗性。Eis 是一种乙酰转移酶,可将 KAN 乙酰化,使其抗菌功能失活。开发 Eis 抑制剂作为 KAN 辅助治疗剂是预防和克服 KAN 耐药性的一条有吸引力的途径。我们发现抗精神病药物氟哌啶醇 (HPD, 1 ) 是一种有效的 Eis 抑制剂,IC 50= 0.39 ± 0.08 μM。我们确定了 Eis-氟哌啶醇 ( 1 ) 复合物的晶体结构,该复合物指导了 34 种类似物的合成。构效关系研究表明,除氟哌啶醇 ( 1 ) 外,还有 8 种类似物,其中一些小于1,可有效抑制 Eis (IC 50 ≤ 1 μM)。确定了 Eis 与三种强效类似物和氟哌利多 (DPD)(一种
