alsactide alsactide alsactide (inn) (brand name synchrodyn 1-17 or simply synchrodyn, former development code name hoechst 433), also known as alisactide, is a synthetic peptide and analogue of adrenocorticotropic hormone (acth) which is used in italy as a diagnostic agent in kidney function for adrenal insufficiency. like acth, alsactide is thought to act as a non-selective agonist of the melanocortin receptors, including the acth receptor (mc2r). however, it appears to show a different profile of receptor selectivity relative to acth, as it apparently demonstrated no evidence of inhibition of endogenous acth in addison's disease patients. alsactideclinical dataatc codev04ch04 (who) identifierscas number34765-96-3 ypubchem cid16129705chemspider17286506uniij0k70h3420keggd07417 ycomptox dashboard (epa)dtxsid90188321 echa infocard100.047.442 chemical and physical dataformulac99h155n29o21smolar mass2119.57 g·mol−13d model (jsmol)interactive image smiles /n=c(\n)/nccc(c(=o)n(cc1cc2c1cccc2)c(=o)ncc(=o)n(ccccn)c(=o)n3ccc3c(=o)n(c(c)c)c(=o)ncc(=o)n(ccccn)c(=o)n(ccccn)c(=o)n(ccccn)c(=o)nccccn)nc(=o)(cc4ccccc4)nc(=o)(cc5cnc5)nc(=o)(ccc(=o)o)nc(=o)(ccsc)nc(=o)(co)nc(=o)(cc6ccc(cc6)o)nc(=o)ccn inchi inchi=1s/c99h155n29o21s/c1-59(2)84(97(148)113-56-81(132)115-68(26-10-14-40-101)87(138)119-69(27-11-15-41-102)88(139)118-67(25-9-13-39-100)85(136)109-45-18-17-43-104)127-96(147)79-30-20-47-128(79)98(149)73(28-12-16-42-103)116-82(133)55-112-86(137)76(51-62-53-111-66-24-8-7-23-65(62)66)124-89(140)70(29-19-46-110-99(106)107)120-93(144)75(49-60-21-5-4-6-22-60)123-94(145)77(52-63-54-108-58-114-63)125-90(141)71(35-36-83(134)135)121-91(142)72(38-48-150-3)122-95(146)78(57-129)126-92(143)74(117-80(131)37-44-105)50-61-31-33-64(130)34-32-61/h4-8,21-24,31-34,53-54,58-59,67-79,84,111,129-130h,9-20,25-30,35-52,55-57,100-105h2,1-3h3,(h,108,114)(h,109,136)(h,112,137)(h,113,148)(h,115,132)(h,116,133)(h,117,131)(h,118,139)(h,119,138)(h,120,144)(h,121,142)(h,122,146)(h,123,145)(h,124,140)(h,125,141)(h,126,143)(h,127,147)(h,134,135)(h4,106,107,110)/t67-,68-,69-,70-,71-,72-,73-,74-,75-,76-,77-,78-,79-,84-/m0/s1key:didcgvralankiu-oteffyefsa-n (verify)
