PEG-poly(amino acid) block copolymer micelles for tunable drug release

Purpose: To achieve tunable pH-dependent drug release in tumor tissues. Methods: Poly(ethylene glycol)-poly(aspartic acid) [PEG-p(Asp)] containing 12 kDa PEG and pAsp (5, 15, and 35 repeating units) were prepared. Hydrazide linkers with spacers [glycine (Gly) and 4-aminobenzoate (Abz)] were introduced to PEG-p(Asp), followed by drug conjugation [doxorubicin (DOX)]. The block copolymer-drug conjugates were either reconstituted or dialyzed in aqueous solutions to prepare micelles. Drug release patterns were observed under sink conditions at pH 5.0 and 7.4, 37C, for 48 h. Results: A collection of six block copolymers with different chain lengths and spacers was synthesized. Drug binding yields were 13-43.6%. The polymer-drug conjugates formed <50 nm polymer micelles irrespective of polymer compositions. Gly-introduced polymer micelles showed marginal change in particle size (40¡À10 nm), while the size of Abz-micelles increased gradually from 10 to 40 nm as the polymer chain lengths increased. Drug release patterns of both Gly and Abz micelles were pH-dependent and tunable. The spacers appear to play a crucial role in controlling drug release and stability of polymer micelles in combination with block copolymer chain lengths. Conclusion: A drug delivery platform for tunable drug release was successfully developed with polymer micelles possessing spacer-modified hydrazone drug-binding linkers. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 13590-42-6, and how the biochemistry of the body works.Synthetic Route of 13590-42-6

A Novel Allyl Transfer Coupled with a Grob Fragmentation

A novel acid-promoted rearrangement is disclosed. In the previously unknown transformation, an allyl group migrated to an in situ formed carbocation stabilized by an electron-rich aryl or heteroaryl group, resulting in a stereoselective intramolecular Grob fragmentation. The outcome of the rearrangement observed with an array of substrates can be satisfactorily rationalized using a working hypothesis with the aid of a six-membered transition state similar to those proposed for the anionic oxy-Cope or oxonia-Cope rearrangements, but involving only one instead of two double bonds.

An efficient one-pot oxidative esterification of aldehydes to carboxylic esters using B(C6F5)3-TBHP

A simple and efficient protocol for oxidative esterification of diverse aldehydes with alcohols was accomplished with tert-butyl hydroperoxide and 1 mol % of tris(pentafluorophenyl)borane [B(C6F5)3] to generate the corresponding esters in good to excellent yields. The present protocol represents compatibility with wide range of functional groups as well as exceptional tolerance toward acid labile protecting groups such as TBDPS, TBDMS, acetonide, and Boc.

Conjugate addition of lithiated (S)-4-isopropyl-3-[(methylthio)methyl]-5,5-diphenyloxazolidin-2-one to cinnamoyl derivatives: Preparation of enantiomerically pure 1,4-diols

The Li derivative of (S)-4-isopropyl-3-[(methylthlio)methyl]-5,5-diphenyloxazolidin-2-one (Li-2; synthetically equivalent to a chiral formyl anion) adds to enones and enoates in a 1,4-fashion. Best results are obtained with 1,3-diarylpropenones (chalcones; Scheme2), trityl enones, and 2,6-di(tert-butyl)-4-methoxyphenyl cinnamates (Scheme 3), with yields up to 80% and diastereoselectivities up to and above 99: 1 of the products (5a – f and 8a,b,e) containing three stereogenic centers! X-Ray crystal-structure analysis reveals that the C,C-bond formation occurs preferentially with relative topicity ul (Re/Si; Fig. 2). The MeS group of the 1.4-adducts can be replaced by RO groups in Hg2¡Â-assisted substitutions, with subsequent removal and facile recovery of the chiral auxiliary (Schemes 4-6). 4-Hydroxycarbonyl derivatives (‘homoaldols’) and mono-, di-, and trisubstituted 1,4-diols are, thus, accessible in enantiomerically pure forms (cf. 15, 16, and 18-20).
