Neuromuscular blocking agents. Some approaches to short acting compounds
摘要:
A series of amidic and N-methylamidic methyl and trideuteromethyl quaternary analogues of atracurium have been prepared. All were less potent and longer acting neuromuscular blocking agents than atracurium, and all showed appreciable vagal blockade at neuromuscular blocking doses. Replacement of NCH3 by NCD3 failed to affect potency. Fluorosubstitution in the central chain did not reduce duration of action. Attachment of acyloxy substituents to the interquaternary chain of atracurium and related compounds adjacent to their ester groups shortened the duration of action significantly. Diformyloxy substitution was the most effective in reducing duration without adversely affecting other properties apart from potency, which was significantly less than that of atracurium.

The present disclosure relates to bifunctional compounds, which find utility as modulators of enhancer of zeste homolog 2 (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

The description relates to Inhibitors of Apoptosis Proteins (IAPs) binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the description provides compounds, which contain on one end a ligand which binds to the IAP E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.
