...Male Sprague-Dawley rats were given 0.051, or 5.1 mmol/kg (14)C labeled bis(2-methoxyethyl)ether orally.

Smaller amounts of N-(methoxyacetyl)glycine, diglycolic acid, 2-methoxyethanol, and 2-(2-methoxyethoxy)ethanol were found.

First Aid: Have the product container or label with you when calling a poison control center or doctor, or going for treatment. If swallowed: Call poison control center or doctor immediately for treatment advice. Do not give any liquid to the person. Do not induce vomiting unless told to do so by the poison control center or doctor. Do not give anything by mouth to an unconscious person. If inhaled: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial respiration, preferably by mouth-to-mouth, if possible. Call a poison control center or doctor for further treatment advice. If on skin or clothing: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control center or doctor for further advice. If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Call a poison control center or doctor for treatment advice. NOTE TO PHYSICIAN: This product is a petroleum distillate. Vomiting may cause aspiration pneumonia. /Phillips Fuel Additive 56 MB/

To assist evaluation of the hazards of skin contact with selected undiluted glycol ethers, their absorption across isolated human abdominal epidermis was measured in vitro. Epidermal membranes were set up in glass diffusion cells and, following an initial determination of permeability to tritiated water, excess undiluted glycol ether was applied to the outer surface for 8 hr. The appearance of glycol ether in an aqueous receptor phase bathing the underside of the epidermis was quantified by a gas chromatographic technique. A final determination of tritiated water permeability was compared with initial values to establish any irreversible alterations in epidermal barrier function induced by contact with the glycol ethers. 2-methoxyethanol (EM) was most readily absorbed (mean steady rate 2.82 mg/sq cm/hr), and a relatively high absorption rate (1.17 mg/sq cm/hr) was also apparent for 1-methoxypropan-2-ol (PM). There was a trend of reducing absorption rate with increasing molecular weight or reducing volatility for monoethylene glycol ethers (EM, 2.82 mg/sq cm/hr; 2-ethoxyethanol, EE, 0.796 mg/sq cm/hr; 2-butoxyethanol, EB, 0.198 mg/sq cm/hr) and also within the diethylene glycol series: 2-(2-methoxyethoxy) ethanol (DM, 0.206 mg/sq cm/hr); 2-(2-ethoxyethoxy) ethanol (DE, 0.125 mg/sq cm/hr) and 2-(2-butoxyethoxy) ethanol (DB, 0.035 mg/sq cm/hr). The rate of absorption of 2-ethoxyethyl acetate (EEAc) was similar to that of the parent alcohol, EE. Absorption rates of diethylene glycol ethers were slower than their corresponding monoethylene glycol equivalents. Combination of intrinsic toxicity and ability to pass across skin contribute to assessment of hazards of contact with undiluted glycol ethers.
The toxicity of bis(2-methoxyethyl)ether was studied in rats. Male Sprague-Dawley rats were given 0.051, or 5.1 mmol/kg (14)C labeled bis(2-methoxyethyl)ether orally. The principal urinary metabolites were (2-methoxyethoxy)acetic acid and methoxyacetic acid which accounted for around 70 and 6% of the doses, respectively. Smaller amounts of N-(methoxyacetyl)glycine, diglycolic acid, 2-methoxyethanol, and 2-(2-methoxyethoxy)ethanol were found. Only unchanged bis(2-methoxyethyl)ether was found in the volatile organic fraction of the expired air. Additionally, rats were given up to 20 daily doses of 5.1 mmol/kg 2-(2-methoxyethoxy)ethanol or (2-methoxyethoxy)acetic acid at on days 3 through 21. 2-(2-Methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid induced no gross or histopathological testicular changes. Bis(2-methoxyethyl)ether metabolism proceeds primarily through an O-demethylation pathway, followed by oxidation to (2-methoxyethoxy)acetic acid. The lack of toxicity of 2-(2-methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid suggests that the testicular toxicity of bis(2-methoxyethyl)ether may be due to methoxyacetic acid, a minor metabolite.

colchicine exert their therapeutic effect by changing the dynamics of tubulin and its polymer form, microtubules. The identification of tubulin as a potentialtarget for anticancer drugs has led to extensive research followed by clinical development of numerous compounds from several families. In this paper we report on the design, synthesis and in vitro evaluation of a group of thiocolchicine derivatives
