生物活性

PKI 14-22 amide, myristoylated TFA is a selective, cAMP-dependent, competitive PKA inhibitor with Ki=~36 nM. The myristoylation modification of PKI 14-22 amide, myristoylated TFA makes it more permeable to cell membranes and blood-brain barriers than the precursor molecule. PKI 14-22 amide, myristoylated TFA can block the phosphorylation of cAMP-dependent downstream targets (such as CREB). PKI 14-22 amide, myristoylated TFA can prevent the development of analgesic tolerance in mice, and also inhibits protein translation and negative-strand RNA synthesis of Zika virus. PKI 14-22 amide, myristoylated TFA can be used in research fields such as opioid tolerance mechanisms and antiviral drugs[1][2][3].

体外研究
(In Vitro)

PKI 14-22 amide,myristoylated TFA (20-40 μM;72 h) 显著抑制 HUVEC 和星形胶质细胞中 Zika 病毒复制,病毒滴度降低超 85%,且不显著导致细胞毒性[2]
PKI 14-22 amide,myristoylated TFA (10-40 μM;4-24 h) 抑制病毒结构蛋白 (capsid/NS1) 表达及正负链 RNA 合成[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[2]

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.
体内研究
(In Vivo)

PKI 14-22 amide,myristoylated (5 nmol/只;脑室内注射;3次:1次/术前 1 小时 + 2 次/术后 24、48 h) TFA 在小鼠吗啡耐受模型中,完全预防吗啡镇痛耐受的发展,但不影响 Naloxone (HY-17417A) 诱导的戒断反应[3]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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).

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.
