Reveromycin A (RM-A) (1) has a 6,6-spiroacetal core structure that is important for its biological activity. However, 1 undergoes a spiroacetal rearrangement to form RM-B (2) with a 5,6-spiroacetal core, which exhibits reduced bioactivity. This undesired rearrangement is partly due to the hemisuccinate moiety at the C18 position of 1.

Streptomyces sp. SN-593, a reveromycin producer, was previously thought to belong to the genus Streptomyces based on its morphological and chemotaxonomic characteristics. In this paper, we re-considered its taxonomic position according to the current criteria.

ReveromycinA (RMA) was developed and is a unique agent for inhibiting osteoclast activity. In a previous study, we experimentally induced periodontal disease in a high-turnover osteoporosis osteoprotegerin-knockout mice (OPG KO) model and found that intraperitoneal administration of RMA inhibited alveolar bone resorption. We prepared a novel RMA-containing ointment for topical non-invasive administration in the oral cavity, in preparation for possible future clinical application.

Introduction: Osteoprotegerin-deficient mice develop severe high-turnover osteoporosis with porous low-density trabecular bone from an age-related increase in osteoclast activity and are useful alveolar bone models of osteoporosis or frail periodontal tissue. Bisphosphonate (BP), a first-line drug for osteoporosis, is bone-avid, causing side effects such as brittle and fragile bones and jaw osteonecrosis after tooth extraction. In orthodontics, active movement is precisely controlled by temporarily suppressing and resuming movement.
