Abstract:
Methods are provided for using doxorubicin active agents in which reduced host toxicity is observed. Aspects of the methods including administering to a subject an effective amount of a doxorubicin active agent in conjunction with a doxorubicin toxicity-reducing adjuvant, e.g., a nitrone compound, or a nitrone compound in combination with a bisdioxopiperazine compound. Also provided are compositions for use in practicing the subject methods. The methods and compositions find use in a variety of different applications, including in the treatment of a variety of different disease conditions.

Abstract:
The present invention relates to novel 5,6-dihydropyrone derivatives and related structures which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The 5,6-dihydropyrone derivatives are useful in the development of therapies for the treatment of bacterial and viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized 5,6-dihydropyrones and of related structures.
Abstract:
The present invention relates to novel synthetic aspirin-mimics that mimic the molecular structure of aspirin, with sulfur to replace oxygen in the key functional groups of aspirin. The novel synthetic aspirin-mimics in this invention integrate multiple features/functions: 1. they are considered as "druggable", as they resemble aspirin in structure; 2. they possess the strongest possible capability as scavengers for free radicals; 3. they could reinstate some damaged proteins/enzymes via the mechanism of thiol-disulfide exchange; 4. they are better chelators to heavy metals and could efficiently remove heavy metals out of body, compared to aspirin. This invention is also directed to novel aspirin-mimics as both drugs and prodrugs, their rational design, their feasible preparation routes by means of synthetic organic chemistry, and their potential therapeutic uses including but not limited to, in treatment and/or prevention of major diseases associated with oxidative stress, such as Alzheimer's disease, Parkinson's disease, cancers, diabetes, cardiovascular disease, renal disease, HIV, pain, hypertension, hypercholesterolemia, hyperlipidemia, rheumatoid arthritis, inflammation, aging, stroke, cataract, glaucoma, age-related macular degeneration, depression, acne, etc.
Abstract:
The present invention relates to synthetic organic antioxidants of small molecules. The novel dithiol-containing compounds in this invention possess strongest possible capability as both scavenger for free radicals and antioxidant. This invention is directed to novel molecules as prodrugs of the novel dithiol-containing compounds, their rational design, their feasible preparation route by means of synthetic organic chemistry, and their potential uses in application to treatment and/or prevention of major diseases associated with oxidative stress, such as Alzheimer's disease, Parkinson's disease, cancer, diabetes, HIV, acne, cardiovascular disease, renal disease, hypertension, hypercholesterolemia, hyperlipidemia, rheumatoid arthritis, inflammation, pain, aging, stroke, cataract, glaucoma, age-related macular degeneration, etc.
Abstract:
The invention provides a lubricating composition containing an oil of lubricating viscosity and a sulfurized aromatic amine compound, especially sulfur coupled aniline. The invention further relates to methods of lubricating an internal combustion engine by supplying the described lubricating composition to the internal combustion engine. The invention further relates to the use of the sulfurized aromatic amine compound as a TBN booster and an antioxidant.
Abstract:
The invention aims at providing novel sulfur compounds, molecular compounds containing the same as the component compound, and so on. The above aim is achieved by using sulfur compounds of the general formula (I) wherein Rs are each independently hydrogen, optionally substituted C1-6 alkyl, optionally substituted C2-6 alkenyl, optionally substituted aryl, chloro, or bromo; m is an integer of 0, 1, or 2; and Z is a group represented by any of the general formulae (II) to (V) (wherein R and m are each as defined above; W is hydrogen or C1-6 alkyl; and Y is a direct bond, C1-3 alkylene, or phenylene).
