MKK7-COV-9 is a potent and selective covalent inhibitor of MKK7 and targets a specific protein–protein interaction of MKK7. MKK7-COV-9 blocks primary B cell activation in response to LPS with an EC₅₀ of 4.98 μM^[1].

Due to poor permeability, the piperidine analogs MKK7-COV-10 and MKK7-COV-11 proves to be inactive in ICW in 3T3 cells, as well as the carboxylic acid MKK7-COV-8. In contrast, as an amide counterpart , MKK7-COV-9, retains activity (EC₅₀=4.06 μM) and furthermore now provides a new vector for further derivatization^[1].
MKK7-COV-9 (10 μM; 48 hours) shows limited cytotoxic effect only at the highest tested concentration. Only one cell line, HCT116, displayed half-maximal lethal dose (LD₅₀)<10 μM for these two compounds^[1].
MKK7-COV-9 (10 μM; 2 hr pre-incubation) is able to inhibit 60% of the CD86⁺ response in response to LPS stimulation, in primary mouse B cells , except the negative control MKK7-NEG-1^[1].
JNK is known to mediate activation of B cells in response to lipopolysaccharide (LPS; HY-D1056) through the TLR4 signaling pathway.
MKK7-COV-9 (0-10 μM; 2 hr pre-incubation) is able to mediate activation of B cells in response to LPS through the TLR4 signaling pathway, it shows a dose-response curves for inhibition of LPS induced activation and exhibits an EC₅₀ value of 4.98 μM.(EC₅₀=4.98 μM for MKK7-COV-12; EC₅₀>10 μM for MKK7-COV-7; EC₅₀=2.23 μM for JNK-IN-8)^[1].
