ChemInform Abstract: Synthesis and Reactivity of Alkyl-1,1,1-trisphosphonate Esters The 伪-trisphosphonic acid esters provide a unique spatial arrangement of three phosphonate groups and may represent an attractive motif for inhibitors of enzymes that utilize di- or triphosphate substrates. To advance...

Thus, D-allo-AHDMHA acylates the b-branched D-allo-Thr; its Na is acylated by the diMeGln; and its b-hydroxy function is esterified by the N-alkyl- a-amino acid L-pipecolic acid. Furthermore, the amino function of the diMeGln moiety is acylated by the bulky g-amino-a,b- ...

The presence of the alkyl donor groups containing heteroatom in the oligomers investigated contributes most for the largest values of the β hyperpolarizability observed. The effect of the oligomer chain length on the β magnitude is also investigated. The results demonstrate that the diethynylsilane ...

The copolymers, consisting of monomethoxy poly(ethylene glycol) and alkylamine-grafted poly(L-aspartic acid), were assembled with carbocyanine dyes into the micelles, which exhibited small size, high loading capacity, good stability, sustained release behavior, and enhanced cellular uptake [3]. The...
