In 2019,International Journal of Pharmaceutics (Amsterdam, Netherlands) included an article by Chaudhari, Kapil S.; Akamanchi, Krishnacharya G.. Recommanded Product: 156-87-6. The article was titled 《Novel bicephalous heterolipid based self-microemulsifying drug delivery system for solubility and bioavailability enhancement of efavirenz》. The information in the text is summarized as follows:
There is an increasing demand for new lipidic biocompatible and safe materials for self-microemulsifying drug delivery system (SMEDDS). The present work reports the synthesis, characterization, oral mucosal irritation study, and application of novel erucic acid ester of G0-PETIM dendron based bicephalous heterolipid (BHL) as an oil phase in SMEDDS using Efavirenz (EFA), a BCS class II drug with poor water solubility and poor bioavailability. Studies were conducted to optimize EFA SMEDDS using different ratios of the BHL as oil phase and surfactant: co-surfactant weight ratios (Km). At Km (1.5), the microemulsion was spontaneously formed in water with mean globule size of 22.78 ± 0.25 nm and polydispersity index (PDI) of 0.23 ± 0.031 with high drug loading efficiency of 80.35 ± 3.1%. Standard stability tests were performed on EFA SMEDDS and the results indicated it to be highly stable. The in vitro dissolution profile of EFA SMEDDS showed >95% of the drug release within an hour and expectedly substantial enhancement in in vivo bioavailability was observed; almost 6-fold increase in bioavailability with parameters Cmax 5.2 μg/mL, Tmax 3 h, and AUC(0-∞) 23.48 μg/h/mL resp. as compared the plain suspension of the drug. In conclusion, the BHL can be used effectively as an oil phase in SMEDDS to enhance solubility and bioavailability of BCS Class II drugs. Further, it holds, in general, a great promise as a new excipient for solubility and bioavailability enhancements. The experimental part of the paper was very detailed, including the reaction process of 3-Aminopropan-1-ol(cas: 156-87-6Recommanded Product: 156-87-6)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Recommanded Product: 156-87-6
