Description: MK-7622 is a cholinesterase inhibitor under evaluation for the treatment of Alzheimer's disease. No studies have been published on this compound in the peer-reviewed literature or other publicly available documents. In October 2013, Merck began a Phase 2 trial in the United States to evaluate the compound's tolerability and efficacy as a symptomatic adjunct to donepezil therapy in patients with probable AD as diagnosed by two conventional diagnostic criteria, the NINCDS-ADRDA and DSM-IV.

More Info:

Biological target: MK-7622 (M1 receptor modulator) is a muscarinic M1 receptor positive allosteric modulator.
In vitro activity: To assess the in vitro activity of the M1 PAMs used in this study, compounds were tested using CHO cells stably expressing the M1 receptor. The previously published M1 PAM PF-06764427 [10, 16] (Fig. 1a, left) and Merck’s MK-7622 [27] (Fig.(Fig.1a,1a, right) were evaluated for their ability to mobilize intracellular calcium (Ca2+) in the M1-CHO cells. The raw calcium traces (Fig. 1b) indicate that both PF-06764427 and MK-7622 induce robust increases in Ca2+ mobilization in the absence of an orthosteric mAChR agonist. Interestingly, there is a similar degree of intracellular Ca2+ mobilization with MK-7622 alone (Ago EC50 2930 nM ± 95, Fig. 1d). Both PF-06764427 (PAM EC50 30 nM ± 3, Fig. 1e) and MK-7622 (PAM EC50 16 nM ± 4, Fig. 1f) act as potent and selective [10] (Supplemental Fig. 1) M1 PAMs in the presence of the orthosteric agonist ACh. Therefore, in addition to their PAM activity, both PF-06764427 and MK-7622 have significant intrinsic agonist activity in this cell-based Ca2+ mobilization assay.

In vivo activity: In light of the finding that both PF-06764427 and MK-7622 have robust allosteric agonist activity in both cell line and native tissue assays, it was hypothesized that MK-7622 would induce behavioral convulsions in a manner similar to those observed with PF06764427. Therefore, a dose-escalation study in mice was performed to assess seizure liability of the M1 ago-PAM MK-7622. Consistent with the previous study with PF-06764427, 30 and 100 mg/kg MK-7622 induces robust convulsions that reached stage 5 on the modified Racine scale [16, 26, 32] in wild-type but not M1 KO mice (Fig. 5a). Interestingly, MK-7622 (1, 3, and 10 mg/kg) did not significantly improve performance in the novel object recognition task (p = 0.9110, one-way ANOVA) (Fig. 5c).Collectively, these findings suggest that M1 ago-PAMs, such as MK-7622 and PF-06764427, induce behavioral convulsions that are not observed with PAMs lacking agonist activity such as VU0453595.
