Description

L-365260 hemihydrate is an orally active and selective antagonist of non-peptide gastrin and brain cholecystokinin receptor (CCK-B), with Kis of 1.9 nM and 2.0 nM, respectively. L-365260 hemihydrate interacts in a stereoselective and competitive manner with guinea pig stomach gastrin and brain CCK receptors[1][2][3].

IC50 & Target

Ki: 1.9 nM (gastrin); 2.0 nM (CCK-B)[1].
In Vitro

L-365260 hemihydrate exhibits a similar high affinity for brain CCK-B receptors of rats, mice and man, and a lower affinity for gastrin and brain CCK-B (IC50=20-40 nM) receptors in dog tissues[1].
L-365260 (1 μM) hemihydrate strongly attenuates the CCK8S- and CCK4-mediated depolarization in a different neuron[2].

In Vivo

L-365260 hemihydrate (0.1-30 mg/kg; p.o.) antagonizes gastrin-stimulated acid secretion in mice (ED50=0.03 mg/kg), rats (ED50=0.9 mg/kg) and guinea pigs (ED50=5.1 mg/kg)[1].
L-365260 hemihydrate (0.01-10 mg/kg; s.c.) enhances analgesia induced by a submaximal dose of Morphine (4 mg/kg) in rats[3].
L-365260 hemihydrate (0.2 mg/kg; s.c. twice daily for 5 days) significantly prolongs the duration of Morphine analgesia in rats[3].

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.
