Description

ST 1535 is a potent and orally active A2A adenosine receptor antagonist. ST 1535 shows antiparkinsonian activity and antitremorigenic effects. ST 1535 has the potential for the research of Parkinson’s disease[1][2].

IC50 & Target[1]

A2a adenosine receptor

 

In Vitro

ST 1535 (0-1000 nM) inhibits forskolin (HY-15371)-induced cAMP formation in CHO cells with IC50s of 510, 353, 950, >1000 nM for hA1, hA2A, hA2B, hA3, respectively[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

ST 1535 (0, 5, 10 mg/kg; p.o.) antagonizes catalepsy induced by i.c.v. administration with the A2A adenosine agonist CGS 21680 (HY-13201)[1].
ST 1535 (10, 20, 40 mg/kg; i.p.) increases the number of contralateral turns induced by l-DOPA (HY-N0304) in rats[2].

Animal Model: 5-6 weeks CD1 male mice[1]
Dosage: 0, 5, 10 mg/kg
Administration: P.o.
Result: Antagonized catalepsy induced by i.c.v. administration with the A2A adenosine agonist CGS 21680.
Animal Model: Male Sprague Dawley rats[2]
Dosage: 10, 20, 40 mg/kg
Administration: I.p.
Result: Significantly increased the number of contralateral turns induced by l-DOPA (3 mg/kg i.p.) at 20 and 40 mg/kg.

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.
