Genetic toxicity in vivo
Description of key information
4-(Diethylamino)-alpha,alpha-bis(4-(diethylamino)phenyl)benzenemethanol is not likely to be mutagenic in vitro.
Additional information
Gene mutation in vitro:
Data from target chemical and its read across chemicals have been reviewed and summarized to determine the mutagenic nature of 4-(Diethylamino)-alpha,alpha-bis(4-(diethylamino)phenyl)benzenemethanol:
Gene mutation toxicity was predicted for p,p',p''-tris(diethylamino)trityl alcohol (CAS no 596 -49 -6) using SSS QSAR prediction database, 2016. The study assumed the use of Salmonella typhimurium strain TA100 with S9 metabolic activation system. p,p',p''-tris(diethylamino)trityl alcohol failed to induce mutation in Salmonella typhimurium strain TA100 in the presence of S9 metabolic activation system and hence is predicted to not classify as a gene mutant in vitro.
Gene mutation toxicity was predicted for p,p',p''-tris(diethylamino)trityl alcohol (CAS no 596 -49 -6) using SSS QSAR prediction database, 2016. The study assumed the use of Salmonella typhimurium strain TA1535 without S9 metabolic activation system. p,p',p''-tris(diethylamino)trityl alcohol failed to induce mutation in Salmonella typhimurium strain TA1535 in the absence of S9 metabolic activation system and hence is predicted to not classify as a gene mutant in vitro.
Gene mutation toxicity study was performed (U. S. Department of Health and Human Services, 2004) to evaluate the mutagenic nature of Malachite Green (RA CAS no 569 -64 -2). The study was performed as per the protocol given by Zeiger et al. The material was used at dose levels of 0, 0.1, 0.3, 1.0, 3.3 or 10.0 µg/plate using Salmonella typhimurium strains TA97, TA98, TA100, TA102, TA104, or TA1535 with or without S9 metabolic activation. Preincubation assay was performed and the plates were incubated for 48 hrs before evaluation. The plates were evaluated for a dose dependent increase in the number of revertants. Each trial consisted of triplicate plates of concurrent positive and negative controls and five doses of malachite green chloride. The high dose was limited by toxicity. Malachite green failed to induce mutation in Salmonella typhimurium strains TA97, TA98, TA100, TA102, TA104, or TA1535 with or without S9 metabolic activation and hence is not likely to be mutagenic in vitro.
In another study performed by Au and Hsu (1979), Gene mutation toxicity study was performed to evaluate the mutagenic nature of Malachite green (RA CAS no 569 -64 -2). The chemical was applied at dosage level of 20 μM for 5 hrs to Chinese hamster ovary cells maintained in McCoy 5a medium.Colcemid (0.04 p g / d final concentration) was added to each culture during the last hour of incubation and all cultures were harvested for conventional cytogenetic preparations, stained with Giemsa, and coded. 50 well-spread metaphases were scored for chromosome aberration. The average number of breaks per metaphase was calculated and was used for comparing the clastogenic activities. Malachite green failed to induce chromosomal aberrations in cultured Chinese hamster ovary (CHO) cells incubated for 5 hours at a dose of 20 μM and hence is not likely be mutagenic in vitro.
Salmonella/ mammalian microsome mutagenicity assay was also performed by Bonin et al (1981) to study the mutagenic potential of Patent Blue V (RA CAS 129 -17 -9) both in the presence and absence of metabolic activator S9 mix. To each 2 ml of top agar at 42°C was added 100 µL bacterial broth culture, 100 µL test compound dissolved in DMSO various concentrations, and 500 µL S9 mix as required. Plates were incubated at 37°C for 72 hrs before counting his+revertant colonies and each dose point was determined from at least two plates, unless indicated otherwise. Criteria for mutagenicity were (a) a dose-response and, (b) reproducibility of the result. Dose-responses were not always evident at concentratrations selected for initial testing. Since no mutagenicity was detected, Patent Blue V is negative for the induction of gene toxicity in vitro and hence is not likely to classify for gene mutation in vitro.
In another Salmonella/Mammalian-Microsome Mutagenicity Assay, the study performed by Seifried et al (2006) to determine the mutagenic nature of C.I. Basic Violet 4 (RA CAS no 2390 -59 -2). The study was performed at dose levels of 0.3-100µg/plate using Salmonella typhimurium TA98, TA100, TA1535, TA1537, and TA1538 with and without of metabolic activation system. Concurrent solvent and positive controls were used in the study. C.I. Basic Violet 4 failed to induce mutation in the Salmonella typhimurium TA98, TA100, TA1535, TA1537, and TA1538 with and without of metabolic activation system and hence is not likely to classify as a gene mutant in vitro.
Based on the weight od evidence data summarized, 4-(Diethylamino)-alpha,alpha-bis(4-(diethylamino)phenyl)benzenemethanol is not likely to classify as a gene mutant in vitro.
Justification for classification or non-classification
Based on the weight of evidence data summarized, 4-(Diethylamino)-alpha,alpha-bis(4-(diethylamino)phenyl)benzenemethanol is not likely to classify as a gene mutant in vitro.
