通过灌胃给雄性和雌性大鼠不同剂量的化合物，剂量范围相差300倍，每周进行5次，一年内总共灌胃260次。通过在那时对少量动物进行采样来评估可逆性毒性损伤。其余动物被观察额外的6个月，除非大鼠的状况要求更早进行解剖。检查了38种不同结构的化合物，发现其中10种，包括2-(4-二甲氨基苯乙烯基)苯并噻唑，具有致癌性。

ADMIN BY GAVAGE OF COMPOUNDS AT SEVERAL DOSE LEVELS RANGING 300-FOLD TO MALE & FEMALE RATS WAS PERFORMED 5 TIMES/WK FOR TOTAL OF 260 DOSES IN 1 YEAR. REVERSIBLE TOXIC LESIONS WERE ASSESSED BY SAMPLING SMALL GROUPS OF ANIMALS AT THAT TIME. REMAINDER OF ANIMALS WERE OBSERVED AN ADDNL 6 MONTHS, UNLESS EARLIER AUTOPSY WAS REQUIRED BY CONDITION OF RATS. 38 COMPD OF DIVERSE STRUCTURE WERE EXAMINED & 10 WHICH INCL 2-(4-DIMETHYLAMINOSTYRYL BENZOTHIAZOLE) WERE FOUND TO BE CARCINOGENIC.

  Photoisomerization oftrans-2-[4′-(Dimethylamino)styryl]benzothiazole

  摘要：

  AbstractPhotoreaction of trans‐2‐[4′‐(dimethylamino)styryl]benzothiazole (t‐DMASBT) under direct irradiation has been investigated in dioxane, chloroform, methanol and glycerol to understand the mechanism of photoisomerization. Contrary to an earlier report, isomerization takes place in all these solvents including glycerol. The results show that restriction on photoisomerization leads to the increase in fluorescence quantum yield in glycerol. The results are consistent with the theoretically simulated potential energy surface reported earlier using time‐dependent density functional theory (TDDFT) calculations. DFT calculations on cis isomers under isolated condition have suggested that cis‐B conformer is more stable than cis‐A conformer due to hydrogen‐bonding interaction. In the ground state, cis‐DMASBT is predominantly present as cis‐B. The fluorescence spectra of the irradiated t‐DMASBT suggested that photoisomerization follows not the adiabatic path as proposed by Saha et al., but the nonadiabatic path.
