Synonyms: ATF-936 | compound 10a [PMID: 20158186]
Compound class: Synthetic organic
Comment: ATF936 is an orally bioavailable, negative allosteric modulator (NAM) of the calcium sensing receptor (CaSR) that was developed by Novartis [3]. It acts to promote a rapid and transient release of parathyroid hormone which stimulates a calcilytic effect in vivo [2]. CaSR antagonists/NAMs are being investigated as bone-forming osteoporosis therapeutics.
