Chymotrypsin (MS grade)
Based on 3 publication(s) in Google Scholar
Chymotrypsin (EC 3.4.21.1; Chymotrypsin A) (MS grade) is an orally effective inhibitor targeting molecules such as TLR4, NF-κB, MMP-1, TNF-α, IL-1β, and IL-6. Chymotrypsin (MS grade) downregulates the TLR4/NF-κB signaling pathway, inhibits the release of inflammatory factors, reduces cell infiltration and tissue damage, and also reduces the expression of tumor cell adhesion molecules (such as CD44 and CD54). It can also be specifically detected by fluorescent probes (such as NBD-3). Chymotrypsin (MS grade) has anti-inflammatory, hepatoprotective, joint damage-reducing, liver protection against lipotoxicity, and anti-tumor metastasis functions, and can be used in the research of diseases such as rheumatoid arthritis, non-alcoholic fatty liver disease, and melanoma metastasis. Chymotrypsin (MS grade) can be used in studies of inflammation, edema, and expectoration.

In Vitro
Chymotrypsin (MS grade) mixed with Trypsin (HY-129047) and Papain (HY-P1645) was used as a treatment group in in vitro studies (with a Chymotrypsin (MS grade) content of 0.2 mg/0.1 mL), causing a decrease in CD44 expression in SMMU-2, SK-MEL 28, B16F10 melanoma cells, MOLT 4/8 leukemia cells, and breast cancer cells[3].
Chymotrypsin (MS grade) selectively reduces the density of CD4, CD44, and CD80 molecules in peripheral lymphocytes[3].
Chymotrypsin (MS grade) can be detected by the probe NBD-3 (2 mM), with a detection concentration of 0-6 g/mL and a reaction time of 20 minutes, producing red fluorescence at 634 nm under an excitation wavelength of 550 nm, with a detection limit of 15. ng/mL. Furthermore, its activity can be inhibited by the inhibitor phenylmethylsulfonyl fluoride (PMSF)[4];

Cell Line:SMMU-2 melanoma cells, SK-MEL 28 melanoma cells, MOLT 4/8 leukemia cells, mammary carcinoma cells, peripheral lymphocytes, B16F10 mouse melanoma cells
-
Concentration:Mixture containing chymotrypsin (0.2 mg/0.1 ml), trypsin (0.2 mg/0.1 ml), and papain (0.5 mg/0.1 ml)
-
Incubation Time:
-
Result:Exposure to the mixture of chymotrypsin, trypsin, and papain reduced the expression of CD44 in SMMU-2 melanoma cells, SK-MEL 28 melanoma cells, MOLT 4/8 leukemia cells, mammary carcinoma cells, and B16F10 mouse melanoma cells.
Additionally, it selectively decreased the density of CD4, CD44, and CD80 molecules on peripheral lymphocytes in vitro.
In Vivo
Chymotrypsin (MS grade) (in combination with trypsin, 3 EAU/kg; oral gavage; once daily; 5 weeks) protectes the liver from damage in an olanzapine-induced non-alcoholic steatohepatitis (NASH) model in young adult male albino rats, significantly reducing olanzapine-induced elevated ALT, AST, ALP, total cholesterol, and LDL-C, reducing steatosis scores and hepatocyte necrosis, increasing Ki67 expression, and not affecting the memory function of the rats[2].
Chymotrypsin (MS grade) (mixed with trypsin and papain, 0.2 mg/0.1 mL mixture; rectal administration; twice daily; 100 days) inhibits primary tumor growth, reduces tumor recurrence and metastasis (including lung and distant metastasis), prolongs mouse survival time, and reduced the expression of CD44 and CD54 molecules in tumor cells in a B16 melanoma metastasis model in female inbred C57Bl6 mice[3].
The NBD-3 probe detects endogenous chymotrypsin in mouse liver[4].

Animal Model:Sprague-Dawley rats adjuvant-induced arthritis (AIA) model[1]
-
Dosage:Low dose 0.53 mg/kg, high dose 1.06 mg/kg
-
Administration:
-
Result:Attenuated joint damage of AIA rats, suppressed paw swelling and arthritic scores, and reduced synovial hyperplasia, inflammatory cell infiltration, pannus formation, and bone destruction.
The overproduction of MMP-1, TNF-α, IL-1β, and IL-6 in serum was remarkably attenuated, and the protein levels of TLR4 and NF-κB in synovial tissue as well as the mRNA expression of TLR4, NF-κB, TNF-α, IL-1β, and IL-6 in synovial tissue were substantially declined.

Animal Model:Female inbred C57Bl6 mice (average body weight 18-20 g) syngeneic B16 melanoma metastatic model[3]
-
Dosage:0.2 mg chymotrypsin combined with 0.2 mg trypsin and 0.5 mg papain per 0.1 mL
-
Administration:
-
Result:Inhibited the growth of primary tumors, with the mean tumor size in the treated group (E1) being statistically significantly smaller than that in all control groups. Reduced the number of tumor recurrences (6% in E1 and 2% in E2 vs 30% in C1 and C2) and considerably curtailed metastasis (46% pulmonary metastases in E1 and 68% in E2 vs 95% in C1 and 90% in C2). Extended the survival time of the mice, with the mean survival time of 72.06 days in E1 and 54.92 days in E2, compared to 27.25 days in C1 and 28.65 days in C2, and 46% of mice in E1 and 30% in E2 survived until the end of the 100-day study.
Correlated with a decreased expression of CD44 and CD54 molecules in ascitic tumor cells.

Chymotrypsin (MS grade) purchased from MedChemExpress. Usage Cited in: Nat Protoc. 2025 May;20(5):1158-1195. [Abstract]
Vibrio cholerae cytolysin (VCC) was produced as an inactive pro-toxin (80 kDa), and the mature toxin (65 kDa) was generated through proteolysis by Chymotrypsin (incubated with VCC at 1000:1 molar ratio; room temperature; 2 h). A representative gel for in-house produced His-tagged pro-VCC and its proteolysis activation was shown. Both the toxin purity (the major band was toxin, with few degradation bands) and activation efficiency were satisfactory.
