[0247] Assay of genotoxicity

[0248] The genotoxicity of the example compounds or their salts was evaluated using the SOS-Chromotest, which employs engineered Escherichia coli that express a reporter protein in response to DNA damage. The engineered E. coli were cultivated in Luria Broth and treated with an example compound or its salt. Both example compound 17A and example compound 17C were administered at a final concentration of 12.5 pg / mL, while all other compounds were dosed at a final concentration of 10 pg / mL. A substrate that reacts with the expressed reporter protein was added to the samples, and the absorbance was measured.

[0249] Genotoxicity was assessed using the equation:SOS-induction factor (SOSIF) = (SampleA600 / SampleA420) / (VehicleA600 / VehicleA420).An SOSIF value lower than 1.5 indicated that the compound or salt was non-genotoxic. FIG. 10 presents the SOSIF across various example compounds, with values obtained by expressing a reporter protein in response to DNA damage in an engineered E. coli strain. The genotoxicity was assessed by measuring the absorbance at 420 nm and 600 nm and calculating the SOSIF, which was normalized to the vehicle control (DMSO). While an SOSIF value greater than 1.5 indicates genotoxicity, FIG. 10 reveals that, aside from 4-nitroquinoline 1 -oxide (4NQO), a known mutagen, all example compounds tested were non-genotoxic.

[0250] Assay of measurement of skin sensitization potential

[0251] The potential of the example compounds or their salts to induce skin sensitization was evaluated using the HaCaT-KeratinoSens cell line.

The cell line has been engineered to express luciferase uponP-660561 -PCactivation of the cellular stress Nrf2-ARE pathway. The cells were cultured in DMEM supplemented with 10% FBS and 1% Penicillin / Streptomycin. The upregulation of the luciferase gene upon treatment with the experimental compounds was quantified using the Bright-Glo™ luminescence detection kit from Promega.

[0252] The relative change in skin sensitization induction was calculated using the equation: SampleLUM / VehicleLUM.Scores higher than 1 indicate skin sensitizing potential, while scores near 1 suggest no change in skin sensitization potential. FIG. 11 presents the normalized skin sensitization of various example compounds. The data shows that these compounds do not cause skin sensitization. The HaCaT-KeratinoSens cell line was treated with both cinnamic aldehyde, a known sensitizer, and the example compounds.
