Biological Activity
Dimethoate (0.1-10 μM, 24 h) inhibits cholinesterase (ChE) enzymatic activity in a concentration-dependent manner in pancreatic stellate cells (PSCs)[1].
Dimethoate (10-6-104 μM, 24 h) inhibits carboxylesterase (CbE) in a concentration-dependent manner (IC50 = 0.97 μM) in the PSCs extracts[1].
Dimethoate (0.1-10 μM, 24-96 h) decreases PSCs cell viability[1].
Dimethoate (0.1-10 μM, 1 h) induces reactive oxygen species (ROS) in the mitochondria of PSCs cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:pancreatic stellate cells (PSCs)
-
Concentration:0.1, 1, 10 μM
-
Incubation Time:24, 48, 72, 96 h
-
Result:Decreased cell viability.
Dimethoate (16 mg/kg; single p.o.) has effects on the immune system of female swiss albino mice[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Female swiss albino mice each weighing 25-30 g[3]
-
Dosage:16 mg/kg
-
Administration:Single oral gavage (p.o.)
-
Result:Showed no significant loss of body weight.
Observed a time depended reduction in spleen weigh.
Suppressed the lymphocyte proliferation responses to T-cell mitogen (Phytohemagglutinin, PHA) (HY-N7038) and B-cell mitogen (Lipopolysaccharides, LPS) (HY-D1056).
The percentage of total and active T cells were significantly decreased.
The total antibody and IgM responses to SRBC's were significantly decreased.
Caused a significant decrease in the number of plaque forming cell (PFC / 106 splenocytes) in a time dependent manner.
-
Animal Model:Rattus norvegicus (Wistar strain; 8-10 weeks old; 120 g; males only)[2]
-
Dosage:20, 40, 60 mg/kg
-
Administration:Intraperitoneal injection (i.p.); 24, 48, 72 h
-
Result:Significant micronuclei induction and metaphase chromosome abnormalities in bone marrow cells indicated positive dose response relationship, confirming its genotoxic and cytotoxic potential.
Showed significant mitotic index decrease.
Decreased mitochondrial membrane potential (MMP), affected the cell cycle, and inflicted DNA damage, which led to cellular apoptosis of leukocytes culminating into immunotoxic effects.
