The main metabolic pathway for metabolism of TGME and TGEE (and presumably the category members) is oxidation via alcohol dehydrogenase that leads to the formation of an alkoxy acid. A second important route of metabolism is oxidation by P-450 mixed function oxidases (O-dealkylation) that lead to the formation of triethylene glycol (TEG). TEG may be oxidized to a carboxylic acid.

人类毒性摘录
/流行病学研究/ 乙二醇醚(EGEs)包括二甘醇,用于半导体的制造。对半导体人群的流行病学研究评估了潜在的负面生殖结果。... 在这些研究中,工人接触到的混合物包括二甘醇,但没有单独接触二甘醇。... 通过调查问卷了解受试者关于所从事工作的信息以及对工作环境的工业卫生专家评估来确定EGEs的接触,但没有进行个人或区域接触的测量。认为在制造区的工人接触到了EGEs。对于回顾性研究,通过全面的面访式访谈女性员工,获得了怀孕结果和潜在混杂因素(年龄、吸烟、种族、教育、收入、怀孕年份和压力)的信息。对早期胎儿丢失和生育力(每个月经周期的受孕概率)的前瞻性研究是在五个工厂的女性员工子集中进行的。除了全面访谈外,还收集了为期6个月的每日日记和每日尿液中人绒毛膜促性腺激素(hCG)水平的测量。在回顾性研究中确定的891例医学确认的怀孕中,774例(86.9%)为活产,113例(12.7%)为自然流产,4例(0.4%)为死产。自然流产的总体未调整相对风险(RR)为1.45(95%置信区间[CI] = 1.02-2.05),在调整混杂因素后变化不大(调整后的RR = 1.43;95% CI = 0.95-2.09)。按工作组分层时,光刻组女性工人自然流产的风险统计学上显著增加(RR = 1.67;95% CI = 1.04-2.55),蚀刻组也是如此(RR = 2.08;95% CI = 1.27-3.19)。对于仅在掩模中接触较高水平EGE的女性,自然流产的风险增加了3倍(RR = 3.38;95% CI = 1.61-5.73)。在前瞻性研究中,制造区和非制造区工人之间自然流产的总体率没有检测到统计学上的显著差异,或者当按工作组检查怀孕结果时。然而,接触EGEs的女性工人的受孕能力较低(生育率[FR] = 0.37;95% CI = 0.11-1.19)。 /乙二醇醚/
/EPIDEMIOLOGY STUDIES/ Ethylene glycol ethers (EGEs) including diglyme are used in the manufacture of semiconductors. Epidemiological studies of semiconductor populations evaluated potential adverse reproductive outcomes. ... In each of these studies, workers were exposed to mixtures including diglyme but not to diglyme alone. ... Exposure to EGEs was determined using questionnaires from subjects about the work performed and an assessment of the work environment by industrial hygienists, but no measurements of personal or area exposures were made. Workers in the fabrication area were considered exposed to EGEs. For the retrospective study, information on pregnancy outcomes and potential confounders (age, smoking, ethnicity, education, income, year of pregnancy, and stress) was obtained through a comprehensive interviewer-administered interview of female employees. The prospective study of early fetal loss and fecundity (probability of conception per menstrual cycle) was conducted in a subset of female employees from five plants. Daily diaries and measurements of daily urinary human chorionic gonadotrophin (hCG) levels for 6 months were collected in addition to the comprehensive interview. Of the 891 medically verified pregnancies identified for the retrospective study, 774 (86.9%) were live births, 113 (12.7%) were spontaneous abortions, and 4 (0.4%) were stillbirths. The overall unadjusted relative risk (RR) for spontaneous abortions was 1.45 (95% confidence interval [CI] = 1.02-2.05) and changed little after adjusting for confounders (adjusted RR =1.43; 95% CI = 0.95-2.09). When stratified by work group, the risk of spontaneous abortion was statistically significantly increased for female workers in the photolithography group (RR = 1.67; 95% CI = 1.04-2.55) and in the etching group (RR = 2.08; 95% CI = 1.27-3.19). For women working with higher levels of EGE only in masking, the risk for spontaneous abortion was increased 3-fold (RR = 3.38; 95% CI = 1.61-5.73). In the prospective study, no statistically significant differences were detected in the overall rate of spontaneous abortions between fabrication and non-fabrication workers or when pregnancy outcomes were examined by work group. However, the ability to conceive was lower among female workers exposed to EGEs (fertility rate [FR] = 0.37; 95% CI = 0.11-1.19). /Ethylene glycol ethers/
/LABORATORY ANIMALS: Acute Exposure/ In accordance to the Draize skin irritation test, 2.0 g/kg of /triethylene glycol monoethyl ether/ was applied to intact and abraded skin /of New Zealand white rabbits/ and covered for 24 hours. In the intact skin assay, erythema was observed in 5/5 rabbits,and edema was observed in 2/5 rabbits. In the abraded skin assay, erythema was observed in 5/5 rabbits and edema was observed in 2/5 rabbits. Observations at necropsy included mottled liver (1 animal), white nodules (2 animals), pocked kidneys (2 animals) and dark areas on lungs (1 animal).

Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. invivo) to form a multimer (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding sites on a Bcr-Abl tyrosine kinase.
