    一种多肽桥连的双酰腙连接键应用于醛衍生药物的递送
    摘要:
    一种多肽桥连的双酰腙连接键应用于醛衍生药物的递送,涉及pH响应型双酰腙连接键。该发明涉及一类新的化学连接键,与传统单酰腙键不同,该连接键通过两个酰腙键间的协同稳定作用,使得该类PTA‑linkers在中性(血液循环)或者酸性条件下(肿瘤组织,内含体,溶酶体)都具有超高的稳定性。当桥连双酰腙键的多肽链被特定蛋白酶水解后,两个酰腙键间的协同稳定作用消失,因此在酸性条件又可以具有良好的响应性。以PTA‑linkers作为连接键,设计细胞外和细胞内多肽链定点水解的两种前药分子,两种前药都可以迅速地释放醛衍生药物分子并杀死肿瘤细胞。

    Fragment-Based Design of Symmetrical Bis-benzimidazoles as Selective Inhibitors of the Trimethoprim-Resistant, Type II R67 Dihydrofolate Reductase
    摘要:
    The continuously increasing use of trimethoprim as a common antibiotic for medical use and for prophylactic application in terrestrial and aquatic animal farming has increased its prevalence in the environment. This has been accompanied by increased drug resistance, generally in the form of alterations in the drug target, dihydrofolate reductase (DHFR). The most highly resistant variants of DHFR are known as type II DHFR, among which R67 DHFR is the most broadly studied variant. We report the first attempt at designing specific inhibitors to this emerging drug target by fragment-based design. The detection of inhibition in R67 DHFR was accompanied by parallel monitoring of the human DHFR, as an assessment of compound selectivity. By those means, small aromatic molecules of 150-250 g/mol (fragments) inhibiting R67 DHFR selectively in the low millimolar range were identified. More complex, symmetrical bis-benzimidazoles and a bis-carboxyphenyl were then assayed as fragment-based leads, which procured selective inhibition of the target in the low micromolar range (K-i = 2-4 mu M). The putative mode of inhibition is discussed according to molecular modeling supported by in vitro tests.

These materials include a polymer selected from the group consisting of polyureas, polyurethane, and polyacylhydrazones. New methods to prepare suitable polyacylhydrazones are also provided. Those methods involve mild conditions and result in a soluble polymer that is stable at room temperature and can be incorporated into formulations that can be coated onto microelectronic substrates.
