This invention pertains generally to antibacterial compounds of Formula I,
as further described herein, and pharmaceutically acceptable salts and formulations thereof. In certain aspects, the invention pertains to methods of using such compounds to treat infections such as those caused by Gram-negative bacteria.
A scalable process for the novelmonobactamantibiotic LYS228 has been developed. This paper covers a novel scalable process for producing β-lactam 10 in the multiple kilogram scale. An alternative approach to compound 7 without protecting-group exchange has been demonstrated to enable a shortened synthesis. A scalable process for the side chain 20, which used an alternative reagent to mitigate a safety

Providing new solid forms, salts and polymorphs of 1-(((Z)-(1-(2-aminothiazol-4-yl) -2-oxo-2-(((3S,4R)-2-oxo-4-((2-oxooxazolidin-3-yl)methyl)-1-sulfoazetidin-3-yl) amino)ethylidene)amino)oxy)-cyclopropanecarboxylic acid (referred to herein as compound X), pharmaceutical compositions containing them, and processes for their manufacture and use in therapy.
A newsynthesis of LYS228, fitting for further process development for commercial manufacture, is described. The key features of this synthesis include development of new protocols for acylation reactions, application of an asymmetric hydrogenation via dynamic kinetic resolution, and a late-stage ring closure to form β-lactam 1.
