Genetic toxicity in vitro

Description of key information

Gene mutation toxicity study for target chemical was performed by Michael Murphey-Corb et al.( Environmental Mutagenesis , 1983)to determine the mutagenic nature of N-Methyl-1,3-propanediamine (6291-84-5).Genetic toxicity in vitro study for N-Methyl-1,3-propanediamine was assessed for its possible mutagenic potential. For this purpose Bacterial reverse mutation assay was performed in Salmonella typhimurium LT2 strains TA 1950 (hisG46, uvrB} ; TS24 (hisG46,recA); TA1537 (hisC3076, uvrB, $a); TA1538 (hisD3052, uvrB, $a}; TA1952(hisC3076, uvrB); and mutant hisG46. No mutagenic effect were observed .Therefore N-Methyl-1,3-propanediamine was considered to be non mutagenic. Hence the test substance cannot be classified as gene mutant in vitro.

Gene mutation - in vitro

Various publications were reviewed to determine the mutagenic nature of (3-aminopropyl) (methyl) amine; 3-Amino-1-methylaminopropane Other name; N-Methyl-1,3-propanediamine (6291-84-5). The studies are as summarised below:

Gene mutation toxicity study for target chemical was performed by Michael Murphey-Corb et al.( Environmental Mutagenesis , 1983)to determine the mutagenic nature of N-Methyl-1,3-propanediamine (6291-84-5).Genetic toxicity in vitro study for N-Methyl-1,3-propanediamine was assessed for its possible mutagenic potential. For this purpose Bacterial reverse mutation assay was performed in Salmonella typhimurium LT2 strains TA 1950 (hisG46, uvrB} ; TS24 (hisG46,recA); TA1537 (hisC3076, uvrB, $a); TA1538 (hisD3052, uvrB, $a}; TA1952(hisC3076, uvrB); and mutant hisG46. No mutagenic effect were observed .Therefore N-Methyl-1,3-propanediamine was considered to be non mutagenic. Hence the test substance cannot be classified as gene mutant in vitro.

In a study for structurally and functionally similar read across chemical, Gene mutation toxicity study was performed by Errol Zeiger et al.( Environmental Mutagenesis, 1987)to determine the mutagenic nature of Iminobis 3isopropylamine (56-18-8). The read across substances share high similarity in structure and log kow .Therefore, it is acceptable to derive information on mutation from the analogue substance. Genetic toxicity study for Iminobis 3isopropylamine was assessed for its mutagenic potential .For this purpose Bacterial reverse mutation assay was performed on Salmonella typhimurium TA98, TA100, TA1535, and TA1537.The test material was exposed at the concentration of 0,33,100,333,1000 and1666µg/plate in the absence and presence of S9.No mutagenic effect were observed. Therefore Iminobis 3 isopropylamine was considered to be non mutagenic in Salmonella typhimurium TA98, TA100, TA1535, and TA1537 in the presence and absence of S9. Hence the substance cannot classify as gene mutant in vitro.

In a study for structurally and functionally similar read across chemical, Gene mutation toxicity study was performed by Errol Zeiger et al.( Environmental Mutagenesis, 1987)to determine the mutagenic nature of Dimethylamine (124-40-3). The read across substances share high similarity in structure and log kow .Therefore, it is acceptable to derive information on mutation from the analogue substance. Genetic toxicity study for Dimethylamine was assessed for its mutagenic potential .For this purpose Bacterial reverse mutation assay was performed on Salmonella typhimurium TA98, TA100, TA1535, and TA1537.The test material was exposed at the concentration of -S9;0,33,100,333,1000 and 3333µg/plate in the absence of S9 while 0,10,100,333,1000,2000,3333 and 4500 µg/plate in the presence of S9.No mutagenic effect were observed.Therefore Dimethylamine was considered to be non mutagenic in Salmonella typhimurium TA98, TA100, TA1535, and TA1537 in the presence and absence of S9. Hence the substance cannot classify as gene mutant in vitro.

Based on the data available for the target chemical and its read across substance and applying weight of evidence (3-aminopropyl) (methyl) amine; 3-Amino-1- methylaminopropane  Other name; N-Methyl-1,3-propanediamine (6291-84-5) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro.

Justification for classification or non-classification

Thus based on the above annotation and CLP criteria for the target chemical . (3-aminopropyl) (methyl) amine; 3-Amino-1- methylaminopropane  Other name; N-Methyl- 1,3- propanediamine (6291-84-5) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro.
