The present invention relates to pegylated amino acid compounds of formula (I) and pharmaceutically acceptable salts thereof, wherein X, R1, R2, R3A, R3B and n are as defined herein. The present invention also relates to compositions which comprise a pegylated amino acid compound of the invention or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier, in combination with a high concentration of an active biological ingredient (ABI). In embodiments of the invention, the ABI is an anti-PD-1 antibody or antigen binding fragment thereof that specifically binds human programmed death receptor 1 (PD-1). The invention further relates to methods for lowering the viscosity of an aqueous solution of a pharmaceutical composition comprising adding a compound of the invention to the solution. The invention also provides methods for treating a pathological disease or condition, such as cancer, by administering to a subject in need of such treatment a therapeutically effective amount of a pharmaceutical composition of the invention.

isocyanide‐multicomponentreactions (I‐MCRs). The approach comprises the use of Passerini and Ugi reactions for assembling pseudo‐peptidic scaffolds (i.e., N‐alkylated and depsipeptides, peptoids) on carboxylic acid‐functionalized fullerenes. The method showed wide substrate scope for the oxo and isocyanide components, albeit the Ugi reaction proved efficient only for aromatic amines. The approach was successfully
为了为富勒烯的多样性导向装饰和连接提供一种有效且通用的方法,我们报告了第一个基于异氰酸酯-多组分反应(I-MCR)的C 60衍生化策略。该方法包括使用Passerini和Ugi反应在羧酸官能化的富勒烯上组装假肽支架(即N-烷基化和二肽,类肽)。该方法显示了羰基和异氰酸酯组分的广泛底物范围,尽管已证明Ugi反应仅对芳族胺有效。该方法已成功用于寡肽和聚乙二醇链(PEG)与C 60的连接,以及用于建造双天线以及PEG固定的二聚体富勒烯。对于所分析的所选化合物,形成1 O 2的量子产率显着。
Organocatalytic and Scalable Syntheses of Unsymmetrical 1,2,4,5‐Tetrazines by Thiol‐Containing Promotors
growing application of tetrazine bioorthogonal chemistry, it is still challenging to access tetrazines conveniently from easily available materials. Described here is the de novo formation of tetrazine from nitriles and hydrazine hydrate using a broad array of thiol‐containing catalysts, including peptides. Using this facile methodology, the syntheses of 14 unsymmetric tetrazines, containing a range of
