  Conformationally restricted arginine analogs

  摘要：

  We report the practical synthesis and structural characterization of a set of conformationally constrained protected arginine analogues. These enantiomerically pure analogues have the general structure 1 and are prepared in seven to eight steps from the commercially available isomers of 4-hydroxyproline. These analogues vary in side chain length and in relative and absolute stereochemistry and are suitable for the direct introduction into peptides. The resulting peptide analogues should be useful as enzymatically stable replacements for bioactive peptides and as probes for understanding the conformational aspects of protein-peptide interactions.

  (EN) A chimeric amino acid analogue is provided suitable for incorporating into peptides which compound is represented by formula (1) where P1 and P2 are preferably an amine protecting agents, or P2 may be a protected aminoiminomethyl group, n is 1 and X can be OH, halide, or preferably an activating group suitable for conjugating the compound of formula (1) to a peptide by conventional means. Peptides containing the chimeric amino acid analogue are provided and include a platelet-aggregation inhibitor represented by Aaa1-Cpd1-Gly-Asp-Aaa2 where Aaa1 is Gly or H, Cpd1 is the compound of formula (1) which has been deprotected and Aaa2 is a hydrophobic amino acid, preferably Val. Alternatively, Aaa1 and Aaa2 may be linked through a structure to form a cycle.(FR) Un analogue d'acide aminé chimérique est approprié pour être incorporé dans des peptides et est représenté par la formule (1) dans laquelle P1 et P2 sont de préférence des agents de protection d'amine, ou P2 peut être un groupe aminoiminométhyle protégé, n vaut 1 et X peut être OH, un halogénure ou de préférence un groupe d'activation approprié pour conjuguer le composé de formule (1) avec un peptide par des moyens conventionnels. Des peptides contenant l'analogue d'acide aminé chimérique sont obtenus et contiennent un inhibiteur d'agrégation de plaquettes représenté par Aaa1-Cpd1-Gly-Asp-Aaa2, où Aaa1 représente Gly ou H, Cpd1 est le composé de formule (1) dont la protection a été enlevée et Aaa2 est un acide aminé hydrophobe, de préférence Val. Dans une variante, Aaa1 et Aaa2 peuvent être reliés par l'intermédiaire d'une structure pour former un cycle.

  一个合成了含有共价修饰的氨基酸类似体的结构，可与第(1)式表示的复合物结合，其中式(1)中的P1和P2可为胺保护剂，或P2为受保护的氨基-甲基酰胺基团，n＝1，且X可以是OH、卤代化合物或最好是非Michael亲核结合位点的活性基团。含有该氨基酸类似体的肽可获得，其中含有血小板聚集抑制剂Aaa1-Cpd1-Gly-Asp-Aaa2，在这种情况下，Aaa1代表Gly或H，Cpd1代表式(1)中的相应产物（已解封）、Aaa2为疏水氨基酸，最好为甲硫氨酸(Vall)。另一种情况中，Aaa1和Aaa2通过结构相互连接，以形成一个环状结构。

  The development of a new, targeted drug delivery paradigm coupled to improved PI3K inhibitors (e.g., PI3Kα inhibitors) represents a significant advance in cancer therapy. Provided herein are compounds, such as compounds of Formula (I) and (II), and pharmaceutically acceptable salts, hydrates, solvates, polymorphs, co-crystals, tautomers, stereoisomers, isotopically labeled derivatives, and prodrugs thereof. The compounds provided herein are PI3K (e.g., PI3Kα) inhibitors and are therefore useful for the treatment and/or prevention of various diseases (e.g., proliferative diseases such as cancer). Also provided herein are nanoparticles and nanogels (e.g., P-selectin targeting nanoparticles) comprising PI3K inhibitors, such a compound described herein. In certain embodiments, a nanoparticle or nanogel described herein encapsulates a compound described herein for targeting delivery to cancer cells or tumors.
