What RS-RTA-3 is
LY3437943 is a synthetic GIP/GLP-1/glucagon triple receptor agonist (CAS 2381089-83-2, C256H392N64O79, 4731.2 g/mol). It is a 39-residue peptide with Aib residues, alpha-methyl-leucine and a Lys-conjugated (AEEA)-gamma-Glu-C20 diacid side chain, with a C-terminal serinamide. Studied in metabolic research models. Supplied as a lyophilized powder; purity by HPLC with a certificate of analysis for every lot.
RS-RTA-3 in the literature
Three receptors, one 39-residue chain: LY3437943 is a synthetic GIP/GLP-1/glucagon triple receptor agonist (CAS 2381089-83-2, C256H392N64O79, 4731.2 g/mol). Its backbone carries Aib residues and an alpha-methyl-leucine, a lysine bears an (AEEA)-gamma-Glu-C20 diacid side chain, and the chain closes with a C-terminal serinamide. Among the incretin-class peptides in this catalogue it has the widest receptor coverage: NN9535 (RS-SEM-1) addresses the GLP-1 receptor alone, LY3298176 (RS-TRZ-2) adds GIP, and LY3437943 adds glucagon receptor activity on top of both. Metabolic research models are where it is examined. See NN9535, LY3298176 and LY3437943: A Structural Comparison and GLP-1 and Incretin Peptides: What the Class Actually Is.
RS-RTA-3 in the catalogue
Five vial sizes are listed for RS-RTA-3 within GLP-1 & Metabolic: 10 mg at $95.20 ($9.52/mg), 20 mg at $159.60 ($7.98/mg), 30 mg at $215.60 ($7.19/mg), 48 mg at $397.60 ($8.28/mg) and 60 mg at $361.20 ($6.02/mg). The 10 mg vial is the entry size, and the 60 mg vial carries the lowest per-milligram price of the range. The Ascend Bundle at $170.00 contains LY3437943 alongside other catalogue items, and RS-AMR-SEM is the product most often ordered together with it. Sales are research use only, for buyers aged 21 or over; you can request the current lot's certificate from support before paying.
