key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: data from iCSS CompTox Dashboard. Data Quality 100%. Data manually curated with highest confidence
Principles of method if other than guideline:
Using a high-throughput robotic screening system, IPM was assessed for its potential to disrupt biological pathways (DNA binding, nuclear receptor (non-steroidal and steroidal), cell cycle, cytochrome P450, hydrolase and cell morphology) that may result in toxicity.

Vehicle:
DMSO
Remarks:
0.001 to 100µM
Details on study design:
See enclosed excel file
Details on results:
113 assays were performed, dimethyl disulphide did not induce a positive response. Therefore, there is no evidence that dimethyl disulphide could interfere with the expression of the screened genes.

113 assays were performed, all results are displayed in the enclosed excel file.

IPM did not induce a positive response (see attached figure and table).

Executive summary:

IPM was evaluated in the ToxCast & Tox21 High-throughput Assays to assess its potential to disrupt biological pathways (DNA binding, nuclear receptor (non-steroidal and steroidal), cell cycle, cytochrome P450, hydrolase and cell morphology) that may result in toxicity. 113 assays were performed at concentrations ranging from 0.001 to 100 µM. Cytotoxicity was assessed in 18 assays, and no cytotoxicity was observed. IPM did not induce a positive response in any assay. Therefore, there is no evidence that IPM could interfere with the expression of the screened genes .

Endpoint:

PubChem SID: 17388960 and 144208368
Details on results:
299 bioassays with 311 bioactivity outcomes were retrieved from the PubChem BioAssay data base. IPM was inactive in 299 bioassays, inconclusive in 11 bioassays and 1 was unspecified.

The list of all the assays performed is displayed in the enclosed excel file.

Executive summary:

The PubChem BioAssay database was searched for chemogenomic, medicinal chemistry and functional genomics biological activities. 299 bioassays with 311 bioactivity outcomes were retrieved . IPM was inactive in 299 bioassays, inconclusive in 11 bioassays and 1 was unspecified. IPM had no activity on cell viability assays, no agonist and/or antagonist activities on the peroxisome proliferator-activated receptor alpha (PPARa), delta (PPARd) and gamma (PPARg), androgen receptor (AR), estrogen receptor alpha (ER-alpha), thyroid receptor (TR) and glucocorticoid receptor (GR) signaling pathways.

Description of key information

Propane-2 -thiol is not a respiratory tract irritant after an acute inhalation exposure (Pence, 1983).

 

Propane-2 -thiol was evaluated in the ToxCast & Tox21 High-throughput Assays (US EPA, 2017) to assess its potential to disrupt biological pathways (DNA binding, nuclear receptor (non-steroidal and steroidal), cell cycle, cytochrome P450, hydrolase and cell morphology) that may result in toxicity. 113 assays were performed at concentrations ranging from 0.001 to 100 µM. Cytotoxicity was assessed in 18 assays, and no cytotoxicity was observed. IPM did not induce a positive response in any assay. Therefore, there is no evidence that IPM could interfere with the expression of the screened genes .

 

The PubChem BioAssay database was searched for chemogenomic, medicinal chemistry and functional genomics biological activities with propane-2 -thiol (NCBI, 2017). 299 bioassays with 311 bioactivity outcomes were retrieved . Propane-2 -thiol was inactive in 299 bioassays, inconclusive in 11 bioassays and 1 was unspecified. Propane-2 -thiol had no activity on cell viability assays, no agonist and/or antagonist activities on the peroxisome proliferator-activated receptor alpha (PPARa), delta (PPARd) and gamma (PPARg), androgen receptor (AR), estrogen receptor alpha (ER-alpha), thyroid receptor (TR) and glucocorticoid receptor (GR) signaling pathways.
