-
Paragraph 0218-0220, (2020/04/29)
The invention provides a hydrophilic carbonate type antibody drug conjugate or a pharmaceutically acceptable salt thereof. The hydrophilic carbonate type antibody drug conjugate or the pharmaceutically acceptable salt thereof provided by the invention can be used for effectively releasing drugs in a tumor weakly acidic microenvironment to obtain a better in-vivo drug effect on tumors, and can be used for obtaining very good in-vivo PK under high DAR.

A scalable and modular total synthesis of 3-lipid I and 3-lipid II was accomplished by a novel route involving an efficient solid phase synthesis of the peptide fragment and an effective chemoenzymatic attachment of the second sugar moiety. The generality of this route was further documented by the synthesis of an analogue bearing the pentaglycine interpeptidic bridge modification characteristic for the human pathogen Staphylococcus aureus.

An array of analogues of the wasp toxin philanthotoxin-433, in which the asymmetric polyamine moiety was exchanged for spermine and the headgroup replaced with a variety of structurally diverse moieties, was prepared using parallel solid-phase synthesis a

Bacterial resistance to existing antibiotics poses a serious threat to human health. Because the peptidoglycan surrounding bacterial cells is essential for survival, the enzymes involved in peptidoglycan biosynthesis are attractive targets for the design
Nε-carbonyl> Derivatives of Tri-L-lysine and Tetra-L-lysine as Potential Intermediates in the Block Polymer Synthesis of Macromolecular Drug Conjugates

Tri-L-lysine and tetra-L-lysine derivatives were synthesized with Nε-carbonyl>(Nε-Teoc) protecting groups an all the lysines, or on all but the N-terminal lysine, and with Nα-(tert-butyloxycarbonyl) (Nα-Boc) or Nα-(9-fluorenylmethyloxycarbonyl) (Nα-Fmoc) groups on the N-terminal lysines.Treatment of the Boc/Teoc peptides with p-toluenesulfonic or 2,4,6-trimethylbenzenesulfonic acid led to Boc cleavage with Teoc retention only when the Teoc/Boc ratio was 1:1 or 2:1.In contrast, treatment of the Fmoc/Teoc peptides with liquid ammonia in a sealed vessel cleaved the Fmoc group without significant loss of Teoc groups even when the Fmoc/Teoc ratio was 3:1, showing that Fmoc and Teoc groups provide more selectivity than the Boc and Teoc combination.Nα-Fmoc and Nε-Teoc groups were both stable under catalytic hydrogenolysis conditions.This made it possible to prepare Nα-Fmoc-tri-L-lysine and Nα-Fmoc-tetra-L-lysine derivatives with Nε-Teoc groups on all but the N-terminal lysine and demonstrated that the triad Fmoc/Cbz/Teoc is superior to Boc/Cbz/Teoc in peptide synthesis involving the orthogonal protection strategy.
