Only one FDA-approved β-lactamase inhibitor has ever been orally available: clavulanic acid, approved in 1984. Avibactam, approved by FDA in 2015, is the first of a new class of BLIs called diazabicyclooctanes, or "DBOs". This class has much broader coverage than clavulanic acid but can only be administered by intravenous injection. Herein, we describe the synthesis and testing of the first approved BLI to be rendered orally bioavailable since clavulanic acid (1984).

Hydrates are common in pharmaceutical development, and the formation of hydrates affects the performance of the final product. However, the role that water plays in crystal packing remains unclear. In this study, Avibactam sodium, which has one dihydrate (Form E), one monohydrate (Form A), and two anhydrous forms (Form B and D), was chosen as the model compound to understand this subject. Single crystal structures of four solid forms were obtained and characterized by single X-ray diffraction. The dynamic vapor sorption experiments revealed the moisture-dependent stability increased in the order: Form B A w). The results indicated that both water activities and temperature are vital factors to determine the amount of water molecules existing in crystal lattice. Moreover, to probe the disintegration of water molecules, the dehydration of dihydrate was investigated in detail by solid-state transformation and solvent-mediated transformation experiments. Finally, two-step dehydration and one-step dehydration + recrystallization mechanisms of these different pathways were proposed by analyzing the transformation experiment results and the crystal structure of various solid forms.

An efficient synthesis of avibactam starting from commercially available ethyl-5-hydroxypicolinate was completed in 10 steps and 23.9% overall yield. The synthesis features a novel lipase-catalyzed resolution, in the preparation of (2S,5S)-5-hydroxypiperidine-2-carboxylate acid, which is a valuable precusor of the key intermediate ethyl (2S,5R)-5-((benzyloxy)amino)piperidine-2-carboxylate. An optimized one-pot debenzylation/sulfation reaction, followed by cation exchange, gave the avibactam sodium salt on a 400.0 g scale.
