The fate of phenoxyethanol in rats and humans has been investigated. The rate of intestinal absorption was rapid, with 60-70% of the excreted (14)C detected at 3 hours and > 95% of the total 4-day urinary (14)C detected within the first 24 hr. Trace amounts of radioactivity were detected in feces. Four days after dosing, only trace amounts of radioactivity remained in the carcass, primarily in the liver (< 0.2% of the dose), fat and muscle. At the 4 day point, the (14)C concentration in blood was measured to be only 0.001. The major metabolite of phenoxyethanol is phenoxyacetic acid.

代谢
乙二醇醚的毒性与其通过细胞质醇脱氢酶(ADH;EC 1.1.1.1)和醛脱氢酶(ALDH;1.2.1.3)氧化为相应的醛和甲酸有关。这些化合物的皮肤接触可能导致局部或全身毒性,包括皮肤致敏和刺激、生殖、发育和血液学效应。以前的研究表明,皮肤具有局部代谢施用化学物质的能力。因此,在人类的风险评估中,需要考虑这些化合物经皮吸收过程中的代谢。通过差速离心法从大鼠肝脏、全层皮肤和经皮皮肤中制备细胞质组分。在大鼠皮肤多次接触地塞米松、乙醇或2-丁氧基乙醇(2-BE)后,也制备了细胞质组分。通过紫外分光光度法连续监测这些组分中ADH/ALDH将乙醇、2-乙氧基乙醇(2-EE)、乙二醇、2-苯氧基乙醇(2-PE)和2-BE转化为甲酸的速度,通过340 nm处NAD+到NADH的转化。大鼠肝脏细胞质中ADH氧化速率以乙醇最高,其次是2-EE >乙二醇 >2-PE >2-BE。然而,使用全层和经皮大鼠皮肤细胞质组分时,代谢顺序变为2-BE >2-PE >乙二醇 >2-EE >乙醇,经皮皮肤细胞质的特异活性大约是全层大鼠皮肤的兩倍。这表明ADH和ALDH定位于表皮,表皮在经皮皮肤细胞质中的蛋白质含量比全层皮肤细胞质多。在大鼠肝脏细胞质中,吡唑对ADH氧化的抑制程度以乙醇最高,其次是2-EE >乙二醇 >2-PE >2-BE,但在皮肤细胞质中,它仅抑制了40%的乙醇代谢。双硫仑完全抑制了肝脏和皮肤细胞质组分中的醇和乙二醇醚代谢。尽管在大鼠肝脏中ADH1、ADH2和ADH3在蛋白质水平上表达,但只有ADH1和ADH2被吡唑选择性抑制,它们是优先代谢短链醇而不是中等链长醇的主要同种型。然而,在大鼠皮肤中,ADH1、ADH3和ADH4占主导地位,对吡唑的敏感性不同,负责代谢乙二醇醚。ALDH1是在大鼠肝脏和皮肤细胞质组分中占主导地位的同种型,被双硫仑选择性抑制,并响应这些组织中表达的ADH同种型形成的醛的量。因此,ADH和ALDH对不同碳链长度的醇和乙二醇醚的不同亲和力可能反映了在大鼠肝脏和皮肤中的相对同种型表达。在多次局部接触后,乙醇处理后乙醇代谢增加最多,2-BE处理后2-BE代谢增加最多。乙醇和2-BE可能诱导特定的ADH和ALDH同种型,这些同种型优先代谢短链醇(即ADH1、ALDH1)和较长链醇(即ADH3、ADH4、ALDH1)。使用地塞米松等一般诱导剂处理增强了乙醇和2-BE的代谢,这表明诱导了多种ADH同种型。
The toxicity of glycol ethers is associated with their oxidation to the corresponding aldehyde and alkoxyacetic acid by cytosolic alcohol dehydrogenase (ADH; EC 1.1.1.1.) and aldehyde dehydrogenase (ALDH; 1.2.1.3). Dermal exposure to these compounds can result in localised or systemic toxicity including skin sensitisation and irritancy, reproductive, developmental and hematological effects. It has previously been shown that skin has the capacity for local metabolism of applied chemicals. Therefore, there is a requirement to consider metabolism during dermal absorption of these compounds in risk assessment for humans. Cytosolic fractions were prepared from rat liver, and whole and dermatomed skin by differential centrifugation. Rat skin cytosolic fractions were also prepared following multiple dermal exposure to dexamethasone, ethanol or 2-butoxyethanol (2-BE). The rate of ethanol, 2-ethoxyethanol (2-EE), ethylene glycol, 2-phenoxyethanol (2-PE) and 2-BE conversion to alkoxyacetic acid by ADH/ALDH in these fractions was continuously monitored by UV spectrophotometry via the conversion of NAD+ to NADH at 340 nm. Rates of ADH oxidation by rat liver cytosol were greatest for ethanol followed by 2-EE >ethylene glycol >2-PE >2-BE. However, the order of metabolism changed to 2-BE >2-PE >ethylene glycol >2-EE >ethanol using whole and dermatomed rat skin cytosolic fractions, with approximately twice the specific activity in dermatomed skin cytosol relative to whole rat skin. This suggests that ADH and ALDH are localised in the epidermis that constitutes more of the protein in dermatomed skin than whole skin cytosol. Inhibition of ADH oxidation in rat liver cytosol by pyrazole was greatest for ethanol followed by 2-EE >ethylene glycol >2-PE >2-BE, but it only inhibited ethanol metabolism by 40% in skin cytosol. Disulfiram completely inhibited alcohol and glycol ether metabolism in the liver and skin cytosolic fractions. Although ADH1, ADH2 and ADH3 are expressed at the protein level in rat liver, only ADH1 and ADH2 are selectively inhibited by pyrazole and they constitute the predominant isoforms that metabolise short-chain alcohols in preference to intermediate chain-length alcohols. However, ADH1, ADH3 and ADH4 predominate in rat skin, demonstrate different sensitivities to pyrazole, and are responsible for metabolising glycol ethers. ALDH1 is the predominant isoform in rat liver and skin cytosolic fractions that is selectively inhibited by disulfiram and responds to the amount of aldehyde formed by the ADH isoforms expressed in these tissues. Thus, the different affinity of ADH and ALDH for alcohols and glycol ethers of different carbon-chain length may reflect the relative isoform expression in rat liver and skin. Following multiple topical exposure, ethanol metabolism increased the most following ethanol treatment, and 2-BE metabolism increased the most following 2-BE treatment. Ethanol and 2-BE may induce specific ADH and ALDH isoforms that preferentially metabolise short-chain alcohols (i.e. ADH1, ALDH1) and longer chain alcohols (i.e. ADH3, ADH4, ALDH1), respectively. Treatment with a general inducing agent such as dexamethasone enhanced ethanol and 2-BE metabolism suggesting induction of multiple ADH isoforms.

制备方法与用途

苯氧乙醇

传统防腐剂

苯氧乙醇(Phenoxyethanol)是一种传统防腐剂,为无色稍带黏性的油状液体,具有轻微的芳香气味和火辣味。它微溶于水,基本不溶于矿物油,可与丙酮、乙醇和甘油任意混合。

苯氧乙醇对铜绿假单胞菌(绿脓杆菌)有显著杀灭效果,并能抑制革兰阳性菌及革兰阴性菌的生长。其机制是通过作用于细胞膜增大钾离子的透过率,降低酶活性,从而抑制细胞生长达到抗菌效果。单独使用苯氧乙醇时,低浓度下防腐效果不佳,高浓度又可能引起皮肤刺痛和灼热感,因此需要与其他防腐成分复配使用。

毒性

作为当前防腐剂标准的化合物之一,苯氧乙醇一般不会释放甲醛,相较于会释放甲醛的其他化合物,它是一个更优秀的替代品。根据《化妆品防腐剂的现状与发展》2007版数据显示,苯氧乙醇的大鼠经口半数致死量为3000 mg/kg,小鼠为4000 mg/kg,属于轻度毒性。

合成方法

采用苯酚一环氧乙烷法制备苯氧乙醇:在乙酸钠或氢氧化钠的作用下,苯酚与环氧乙烷缩合。反应后通过粗品减压蒸馏得成品,该工艺中苯酚转化率≥99%,合成收率≥95%,总产品收率达90%。反应方程式如下:

[ \text{Phenol} + \text{EO} \xrightarrow{\text{NaAc/H}_2\text{O}} \text{Phenoxyethanol} ]

此方法需在温度20 ℃和0.2―0.25 MPa的压力下进行,适合大规模工业生产。

化学性质

苯氧乙醇为无色液状液体。熔点14℃,沸点245.2℃。易溶于醇、醚及氢氧化钠溶液,微溶于水,在酸或碱中稳定,并具有芳香气味和烧灼味。

用途

苯氧乙醇是一种高沸点有机溶剂,可用于水性涂料及油墨成膜助剂、香料定香剂、油墨流畅剂、药用防腐杀菌剂、电子清洗剂及油墨慢干剂等。同时,它也具有良好的溶解性能,能与多种树脂如丙烯酸树脂、硝基纤维素、乙基纤维素、环氧树脂、醇酸树脂和苯氧基树脂等多种有机物混溶。

生产方法

由苯酚和环氧乙烷加成而得,在乙酸钠或氢氧化钠存在下反应。反应温度为200℃,压力为0.2-0.25 MPa。

    The present disclosure relates to bifunctional compounds, which find utility as modulators of SMARCA2 or BRM (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand that binds to the Von Hippel-Lindau E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
    本公开涉及双功能化合物,其作为SMARCA2或BRM(靶蛋白)的调节剂具有实用性。具体而言,本公开涉及包含一端结合Von Hippel-Lindau E3泛素连接酶的配体,另一端结合靶蛋白的双功能化合物,使得靶蛋白与泛素连接酶靠近以实现靶蛋白的降解(和抑制)。本公开展示了与靶蛋白降解/抑制相关的广泛药理活性。本公开的化合物和组合物用于治疗或预防由靶蛋白聚集或积累导致的疾病或紊乱。
