Based on 4 publication(s) in Google Scholar

TAK-683 is a potent full KISS1 receptor (KISS1R) agonist (IC₅₀=170 pM) with improved metabolic stability. TAK-683 is a nonapeptide metastin analog, exhibits agonistic activities to KISS1R with EC₅₀ values of 0.96 nM and 1.6 nM for human and rat, respectively. TAK-683 depletes GnRH in the hypothalamus and reduces plasma FSH, LH, and testosterone levels in vivo, it has the potential for the study of hormone-dependent prostate cancer.

Description

TAK-683 is a potent full KISS1 receptor (KISS1R) agonist (IC₅₀=170 pM) with improved metabolic stability. TAK-683 is a nonapeptide metastin analog, exhibits agonistic activities to KISS1R with EC₅₀ values of 0.96 nM and 1.6 nM for human and rat, respectively^[1]. TAK-683 depletes GnRH in the hypothalamus and reduces plasma FSH, LH, and testosterone levels in vivo, it has the potential for the study of hormone-dependent prostate cancer^[1]^[2]^[4].

IC₅₀ & Target

In Vitro

TAK-683 exhibits an IC₅₀ value (95% CI) from receptor binding assays is 150-180 pM and EC₅₀ value (95% CI) from Ca⁺ mobilization assays is 180 (159–203) pM in rat KISS1R-expressing Chinese hamster ovary (CHO) cells^[4].

In Vivo

TAK-683 (subcutaneous injection; 0.008, 0.08, 0.8, or 8 μmol/ml/kg; once daily; 7 days) induces an increase in plasma luteinizing hormone and testosterone levels; however, after day 7, plasma hormone levels and genital organ weights are reduced^[3].
TAK-683 (subcutaneous injection; 10, 30, or 100 pmol/h; once daily; 4 weeks) provides a promising for suppressing reproductive functions and hormone-related diseases such as prostate cancer^[3].
TAK-683 (subcutaneous injection; 2.1-21 nmol/kg/day; once daily; 12 weeks) has a longer-term evaluation in prostate cancer model, serum concentrations of PSA is reduced in rats, PSA concentrations are reduced to below the limit of detection (0.5 ng/ml)) in all rats by day 14^[4].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
