PKI 14-22 amide,myristoylated
Based on 3 publication(s) in Google Scholar
PKI 14-22 amide, myristoylated is a selective, cAMP-dependent, competitive PKA inhibitor with Ki=~36 nM. The myristoylation modification of PKI 14-22 amide, myristoylated makes it more permeable to cell membranes and blood-brain barriers than the precursor molecule. PKI 14-22 amide, myristoylated can block the phosphorylation of cAMP-dependent downstream targets (such as CREB). PKI 14-22 amide, myristoylated can prevent the development of morphine analgesic tolerance in mice, and also inhibits protein translation and negative-strand RNA synthesis of Zika virus. PKI 14-22 amide, myristoylated can be used in research fields such as opioid tolerance mechanisms and antiviral drugs.

Biological Activity
|
Zika virus |
PKI 14-22 amide,myristoylated (20-40 μM; 72 h) significantly inhibits Zika virus replication in HUVEC and astrocytes, reducing viral titers by more than 85% without causing significant cytotoxicity[2].
PKI 14-22 amide,myristoylated (10-40 μM; 4-24 h) inhibits viral structural protein (capsid/NS1) expression and positive and negative strand RNA synthesis[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:HUVEC
-
Concentration:10 μM, 20 μM, 40 μM
-
Incubation Time:48-72 h
-
Result:Significantly reduced expression of viral capsid and NS1 proteins in a dose-dependent manner.
At 40 μM, protein levels were undetectable by 72 hpi, while 10 μM showed partial inhibition.

Animal Model:Male Swiss Webster mice (25-30 g, 6 weeks), morphine tolerance model via 75 mg pellet implantation[3]
-
Dosage:5 nmol/mouse
-
Administration:1 dose (1 h before pellet implantation) + 2 additional doses at 24 h and 48 h post-implantation, total 3 doses over 3 days.
-
Result:In the tail immersion test, morphine-pelleted mice pre-treated with PKI showed no tolerance to morphine’s antinociceptive effect, with ED50 values comparable to naive mice (6.2 vs. 6.6 mg/kg, non-significant difference).
