ly-307,452 ly-307,452 ly-307,452 is a drug used in neuroscience research, which was among the first compounds found that acts as a selective antagonist for the group ii metabotropic glutamate receptors (mglur2/3), and was useful in early studies of this receptor family, although it has largely been replaced by newer drugs such as ly-341,495. its molecular formula is c21h25no4 ly-307,452identifiers iupac name (2s,4s)-2-amino-4-(4,4-diphenylbut-1-yl)pentan-1,5-dioic acid cas number174393-13-6pubchem cid6324634iuphar/bps3350chemspider4884363 nchemical and physical dataformulac21h25no4molar mass355.434 g·mol−13d model (jsmol)interactive image smiles c1=cc=c(c=c1)c(ccc(c(c(=o)o)n)c(=o)o)c2=cc=cc=c2 inchi inchi=1s/c21h25no4/c22-19(21(25)26)14-17(20(23)24)12-7-13-18(15-8-3-1-4-9-15)16-10-5-2-6-11-16/h1-6,8-11,17-19h,7,12-14,22h2,(h,23,24)(h,25,26)/t17-,19-/m0/s1 nkey:dwlovdopfjpwne-hkuynngssa-n n ny (what is this?)
