DFMTI
Based on 1 Customer Validation
DFMTI (MK5435) is a blood-brain barrier-penetrant mGluR1 inhibitor. DFMTI abolishes the tobacco mosaic virus (TMV) resistance phenotype of NbAS-B-overexpressing plants by inhibiting glutamate production required for the activation of the Salicylic acid (HY-B0167) pathway. DFMTI disrupts prepulse inhibition in rats. DFMTI can be used in research related to psychiatric disorders and tobacco mosaic virus infection.

体外実験
DFMTI abolishes the Tobacco Mosaic Virus (TMV) resistance phenotype of Nicotiana benthamiana overexpressing NbAS-B by inhibiting glutamate production required for the activation of the Salicylic acid (HY-B0167) pathway[1].
DFMTI (MK5435) (incubated for 5 min) potently inhibits human mGluR1a-mediated intracellular Ca2+ mobilization in CHO cells, with an IC50 of 4.3 nM, and exhibits low activity against human mGluR5[2].
DFMTI (10 μM) displaces specific [18F]MK-1312 binding in rhesus monkey and human brain slices, and effectively determines the non-displaceable binding of [18F]MK-1312 in rhesus monkey and human cerebellar homogenates, confirming that it interacts specifically with mGluR1 in these tissues[2].
DFMTI (compound 3) potently inhibits glutamate-induced calcium mobilization in TREx293 cells, with IC50 values of 8 nM, 31 nM, 21 nM, and 14 nM in cells expressing rmGlu1 WT, hmGlu1 WT, rmGlu1 V757L, and hmGlu1 L757V, respectively; the potency differs by approximately 4-fold between human and rat wild-type receptors[3].
DFMTI acts as a non-competitive allosteric antagonist against rmGlu1 WT, rmGlu1 V757L, hmGlu1 WT, and hmGlu1 L757V, with subtle variations in its potency depending on the amino acid at position 757[3].

Result:Reduced [18F]MK-1312 uptake in all gray matter brain regions in a dose-dependent manner.
Yielded an Occ50 (plasma concentration for 50% occupancy) of 76 nM via Hill equation modeling of plasma concentration and mGluR1 receptor occupancy relationship.
Required a plasma concentration of 285 nM to achieve 75% mGluR1 occupancy in the cerebellum.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
