Compounds, tautomers and pharmaceutically acceptable salts of the compounds are disclosed, wherein the compounds have the structure of Formula Ia, ##STR00001##
as defined in the specification. Corresponding pharmaceutical compositions, methods of treatment, methods of synthesis, and intermediates are also disclosed.

Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.

The invention relates to compounds of the structure of formula I and II:

where X is selected from the group consisting of O, S and NH; Y, A and B are independently selected from the group consisting of N and CH; D, E and F are independently selected from the group consisting of CH, N, O and S; the symbol ---- represents a single or a double bond; and R.sub.1, R.sub.2 and R.sub.3 are independently selected from the group consisting of H, electron withdrawing groups and electron releasing groups. In other embodiments, the compounds are used as oxygen scavengers and in barrier compositions and articles.

The disclosure includes a method of inhibiting a eukaryotic translation initiation factor 3e (eIF3e) comprising contacting the eIF3e with a compound or salt of the Formula I, where the variables, e.g., Y, Z, R, and R.sup.1R.sup.11 are defined herein. The disclosure includes a method of modulating SIX1 and/or EYA2 levels or inhibiting SIX1/EYA2 interactions comprising contacting eukaryotic translation initiation factor 3e (eIF3e) with a compound of the formula. The disclosure includes a method of treating metastatic breast cancer (of all subtypes), glioblastoma, Wilms' tumor, ovarian cancer, lung cancer, cervical, oral cancer, or any cancer shown to be dependent on SIX1 or EYA proteins, which are regulated by eIF3e, in a patient comprising administering the patient a compound of the Formula I.

A nitrogen-containing derivative of substituted phenol hydroxyl acid ester is represented by formula (I). A salt of the compound of formula (I) has good water solubility, and in vivo, can rapidly and completely release substituted phenols having a pharmacological effect, which can improve the water solubility of substituted phenols, rapidly exert the pharmacological effects of substituted phenols in vivo, and has good safety. The method for preparing the above-mentioned compound is provided. This compound can also be used in the preparation of drugs that produce anaesthesia and/or sedative and hypnotic effects on humans and animals. ##STR00001##
