GL64 is a selective agonist of ADGRD1 (EC50 = 3.98 μM). GL64 has low selectivity for ADGRD2, ADGRG5, ADGRG6, CELSR1, CELSR2, CELSR3, and ADGRG4 isoforms. GL64 activates ADGRD1 by mimicking the satchel sequence. GL64 regulates osteoclast maturation through the cAMP-PKA-NFATC1 pathway. GL64 effectively inhibits osteoclastogenesis and prevents bone loss both in vitro and in vivo. GL64 is useful in the study of osteoclast-related diseases.

Description

GL64 is a selective agonist of ADGRD1 (EC50 = 3.98 μM). GL64 has low selectivity for ADGRD2, ADGRG5, ADGRG6, CELSR1, CELSR2, CELSR3, and ADGRG4 isoforms. GL64 activates ADGRD1 by mimicking the satchel sequence. GL64 regulates osteoclast maturation through the cAMP-PKA-NFATC1 pathway. GL64 effectively inhibits osteoclastogenesis and prevents bone loss both in vitro and in vivo. GL64 is useful in the study of osteoclast-related diseases[1].

In Vitro

GL64 (10 μM) stimulates CRE-luciferase activity by more than 1.5-fold in ADGRD1-overexpressing HEK293T cells[1].
GL64 (10 μM) increases CRE-luciferase and endogenous adenosine cAMP levels in wt MEFs but has no effect on Adgrd1−/− cells[1].
GL64 (0-100 μM) does not increase CRE-luciferase in HEK293T cells overexpressing adhesion GPCRs, such as ADGRD2, ADGRG5, ADGRG6, CELSR1, CELSR2, CELSR3, and ADGRG4, and does not activate nonadhesion GPCRs, including GPR68, NPFFR1, GPR183, and GPRC5B[1].
GL64 has weak agonist activity against ADGRD1 (EC50 = 16.89 μM) in stachel peptide-treated in ADGRD1-overexpressing HEK293T cells[1].
GL64 (10 μM, 6 days) inhibits the differentiation of male WT bone marrow-derived macrophages (BMMs) into mature osteoclasts but has no effect on Adgrd1−/− BMMs[1].
GL64 (10 μM, 6 days) down-regulates the mRNA expression levels of Dc-stamp, Acp5, and Nfatc1, during male mouse osteoclast maturation in BMMs[1].
GL64 (30 μM) increases endogenous cAMP levels in male BMMs[1].
GL64 (10 μM, 2 days) reduces NFATC1 nuclear localization in BMMs[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
