VU6025733 (AG06827) is a highly selective, orally active and blood-brain barrier-penetrant positive allosteric modulator of the muscarinic acetylcholine receptor subtype M4 (M4 mAChR). VU6025733 exerts a potentiating effect on acetylcholine-induced receptor activation with an EC50 of 23 nM for hM4 and 55 nM for rM4. VU6025733 shows high selectivity over other muscarinic acetylcholine receptor subtypes, dose-dependently reduces amphetamine-induced hyperlocomotion in rats. VU6025733 is applicable to the research of schizophrenia, Parkinson's disease, and Alzheimer's disease.

Description

VU6025733 (AG06827) is a highly selective, orally active and blood-brain barrier-penetrant positive allosteric modulator of the muscarinic acetylcholine receptor subtype M4 (M4 mAChR). VU6025733 exerts a potentiating effect on acetylcholine-induced receptor activation with an EC50 of 23 nM for hM4 and 55 nM for rM4. VU6025733 shows high selectivity over other muscarinic acetylcholine receptor subtypes, dose-dependently reduces amphetamine-induced hyperlocomotion in rats. VU6025733 is applicable to the research of schizophrenia, Parkinson's disease, and Alzheimer's disease[1].

In Vitro

VU6025733 (10-point serial dilutions (1:3)) potently potentiates human M4/Gqi5-CHO cells (EC50 = 33 nM) and rat M4/Gqi5-CHO cells (EC50 = 62 nM), while showing no activity in human or rat M1, M2, M3, or M5 muscarinic receptor-expressing CHO cells[1].
VU6025733 inhibits hERG channels with an IC50 of 4.6 μM[1].
VU6025733 induces cytotoxic effects in HepaRG 3D spheroids, including reduced glutathione content and cellular ATP, with MEC values of 9.7 μM and 4.2 μM, respectively[1].
VU6025733 decreases oxygen consumption rate (MEC = 2.0 μM) and increases extracellular acidification rate (MEC = 7.1 μM) in HepG2 cells, indicating electron transport chain inhibition[1].
VU6025733 has high brain penetration potential with no P-glycoprotein efflux, as shown by an efflux ratio of 0.80 and Papp (A-B) of 12.7 × 10-6 cm/s in MDCKII-MDR1 cells[1].
VU6025733 shows minimal inhibition of CYP1A2, CYP2C9, and CYP3A4 (IC50 ≥ 19.3 μM) and moderate inhibition of CYP2D6 (IC50 = 8.4 μM)[1].

In Vivo

VU6025733 (10-30 mg/kg; p.o.; single administration) produces a robust, dose-dependent blockade of induced hyperlocomotion in male Sprague-Dawley rats, with a minimum effective dose of 10 mg/kg and up to 39.7% reversal at the highest tested dose[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.
