The invention relates generally to disulfide drug conjugates wherein a linker comprising a sulfur-bearing carbon atom substituted with at least one hydrocarbyl or substituted hydrocarbyl is conjugated by a disulfide bond to a cysteine sulfur atom of a targeting carrier, and wherein the linker is further conjugated to a drug moiety. The invention further relates to activated linker-drug conjugates suitable for conjugation to a targeting carrier by a disulfide bond. The invention further relates to methods for preparing hindered disulfide drug conjugates.

Compounds of the formula II:
in which R8 is of the formula Q-(X)r-CO- wherein either a) X = - CH2-, r = 1, Q is a pyridinium group and R7 is -SO3- or -OSO3-; or b) X = -SCH2- and r = 1; wherein Q is e.g. 1,2,3,4-tetrazol-5-yl and R7 is -SO3H or -OSO3H; or c) X = -CH2NH2-, r = 1 and Q is e.g.
phenyl or a 5-6-membered heterocycle and R7 is -SO3H or -OSO3H; or d) X = -NH2- and r = 1, wherein Q is e.g. phenyl and R7 is - SO3H or -OSO3H; are beta-lactamase inhibitors. They may be used in combination with monobactams against gram-negative bacteria.
式 II 的化合物:
其中 R8 为式 Q-(X)r-CO-,其中 a) X = -CH2-,r = 1,Q 为吡啶基,R7 为 -SO3- 或 -OSO3-;或 b) X = -SCH2-,r = 1;其中 Q 为 1,2,3,4-四唑-5-基,R7 为 -SO3H 或 -OSO3H;或 c) X = -CH2NH2-,r = 1,Q 为苯基或 5-6 元杂环,R7 为 -SO3H 或 -OSO3H;或 d) X = -NH2-,r = 1,其中 Q 为 1,2,3,4-四唑-5-基,R7 为 -SO3H 或 -OSO3H。
或 d) X = -NH2-,r = 1,其中 Q 是苯基等,R7 是-SO3H 或-OSO3H。它们可与单内酰胺类药物结合使用,以对付革兰氏阴性菌。
