nabitan nabitan nabitan (nabutam, benzopyranoperidine, sp-106, abbott 40656) is a synthetic cannabinoid analog of dronabinol (marinol). it exhibits antiemetic and analgesic effects, most likely by binding to and activating the cb1 and cb2 cannabinoid receptors, and reduced intraocular pressure in animal tests, making it potentially useful in the treatment of glaucoma. nabitanclinical dataatc codenoneidentifiers iupac name 5,5-dimethyl-8-(3-methyloctan-2-yl)-2-(prop-2-yn-1-yl)-1,3,4,5-tetrahydro-2h-benzopyranopyridin-10-yl 4-(piperidin-1-yl)butanoate cas number66556-74-9 ypubchem cid39503chemspider36117 yuniijo7bor6b3ochemical and physical dataformulac35h52n2o3molar mass548.812 g·mol−13d model (jsmol)interactive image smiles o=c(oc2cc(cc1oc(c\3=c(/c12)cn(cc/3)cc#c)(c)c)c(c)c(c)ccccc)cccn4ccccc4 inchi inchi=1s/c35h52n2o3/c1-7-9-11-15-26(3)27(4)28-23-31(39-33(38)16-14-21-36-19-12-10-13-20-36)34-29-25-37(18-8-2)22-17-30(29)35(5,6)40-32(34)24-28/h2,23-24,26-27h,7,9-22,25h2,1,3-6h3 ykey:mcvpmhdadnvrkf-uhfffaoysa-n y (verify) nabitan has the advantage of being water-soluble, unlike most cannabinoid derivatives, and was researched for potential use as an analgesic or sedative, although it was never developed for clinical use and is not currently used in medicine, as dronabinol or nabilone were felt to be more useful. however it is sometimes used in research into the potential therapeutic applications of cannabinoids.
