In Vivo Efficacy Study

: Caffeic acid purchased from MedChemExpress. Usage Cited in: Pestic Biochem Physiol. 2025 Dec:215:106655.; Immunostaining with anti-mCherry antibody to detect the effect of Caffeic acid (2 mg/mL) on Methoprene-induced nuclear localization of Met at 96 h AEL. Caffeic acid effectively prevented the Methoprene-induced nuclear import of Met at 96 h AEL in the larvae of D. melanogaster Met-mCherry.

: Caffeic acid purchased from MedChemExpress. Usage Cited in: Pestic Biochem Physiol. 2025 Dec:215:106655.; Caffeic acid (1–1000 μM) inhibited the Methoprene-induced JHRR-Luc expression and Met-Tai interaction in a dose-dependent manner.

: Caffeic acid purchased from MedChemExpress. Usage Cited in: Pestic Biochem Physiol. 2025 Dec:215:106655.; Co-immunoprecipitation assays were performed to detect the effect of Caffeic acid (10 μM; 1 h) on the interaction between Met and Hsp83. Caffeic acid promoted the binding between Met and Hsp83.

: Caffeic acid purchased from MedChemExpress. Usage Cited in: Pestic Biochem Physiol. 2025 Dec:215:106655.; The binding and competition curves of Met and Methoprene were shown. Caffeic acid (2 μM) inhibited the interaction between Met and Methoprene.

: Caffeic acid purchased from MedChemExpress. Usage Cited in: Pestic Biochem Physiol. 2025 Dec:215:106655.; 2 mg/mL Caffeic acid (0.5-2.0 mg/mL) resulted in significantly precocious pupation, and smaller pupae of O. furnacalis compared to controls.

In Vitro

Caffeic acid has inhibitory effects on histamine-induced responses and the inhibitory effect of Caffeic acid is gradually increased when the concentration used for pretreatment is increased from 0.1 to 1 mM, similar to typical dose-dependent responses. Pretreatment of HEK293T-TRPV1 cells with 1 mM Caffeic acid results in significant inhibition of capsaicin-induced responses. When lower concentration of Caffeic acid is used, the inhibitory effect for capsaicin-induced responses is less evident. Calcium imaging experiments show that Caffeic acid incubation results in significant inhibition in histamine-sensitive dorsal root ganglion (DRG) neurons. Pretreatment with Caffeic acid (1 mM) results in a significant decrease in the percentage of responsive DRG neurons to histamine application from 12.5% to 2.1%. Pretreatment with 1 mM Caffeic acid dramatically blocks the allylisothiocyanate (AITC)-induced intracellular calcium increase in TRPA1-expressing cells. Caffeic acid is also able to block the AITC-induced activation of TRPA1^[1].

In Vivo

Mice pretreated with Caffeic acid (500 mg/kg) exhibit significantly less histamine-induced scratching (30.50±10.87 bouts/1 h, n=6). It is further found that the lower dose of Caffeic acid (100 mg/kg) is not significantly effective in terms of anti-scratching effects in histamine-induced scratching, although there appears to be a tendency of reduction (49.40±12.35 bouts/1 h, n=5). The chloroquine induced scratching is significantly inhibited by pretreatment with 500 mg/kg of Caffeic acid (161.6±31.42 bouts/1 h, n=5)^[1].Caffeic acid significantly reduces the expression of 5-LO mRNA (P<0.01) dose-dependently in hippocampus. Compare with the ischemia-reperfusion (I/R) non-treated group, 5-LO protein expression is significantly reduced in the I/R-Caffeic acid group (P<0.05 or P<0.01), especially in the I/R-Caffeic acid group (50 mg/kg). Compare with the I/R non-treated group, the latency to find platform is significantly shortened in low- and high-dose Caffeic acid groups, the shortened platform latency is most evident in the I/R- Caffeic acid group (50 mg/kg) (P<0.01). In the low-dose Caffeic acid group, cell injury is still marked, the pyknosis ratio is (63.6±2.8)%, whereas in the high-dose Caffeic acid group, hippocampal neuron karyopyknosis is significantly reduced and the pyknosis ratio is (13.3±3.0)%^[2].

Cell Assay ^[1]	To determine cell viability, MTT assay is performed. HEK293T cells are cultured in 96-well plate at 37°C, a day before so that the confluence of cell is 85 to 90% on the actual day of the experiment. On the day of the experiment the cells are treated with different concentration of Caffeic acid for 10 min. Control cells are treated only with media. After removing supernatant and washing with PBS, MTT reagent (5 mg/mL) is added directly to fresh media. Cells are then incubated at 37°C for additional 4 h followed by draining of the media and overnight storage in dark condition. The next day, DMSO is added to each well and mixed in shaker for 10 min after which plate is read using microplate recorder at 490 nm with a reference wavelength of 620 nm. The relative cell viability (%) is expressed as a percentage relative to the untreated control cells^[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration ^[2]	Rats are divided into five groups: the sham group (n=9), ischemia-reperfusion (I/R) non-treated group (n=9), I/R-Caffeic acid group (10 mg/kg) (n=9), I/R-Caffeic acid group (30 mg/kg) (n=9) and I/R- Caffeic acid group (50 mg/kg) (n=9). In I/R-Caffeic acid groups, the rats are administrated Caffeic acid at 10, 30, 50 mg/kg (prepared with 0.3% sodium carboxymethyl cellulose) by intraperitoneal injection at 30 min prior to ischemia. The sham group and I/R group are treated with an equal volume of 0.3% sodium carboxymethyl cellulose^[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
