摘要:
Niclosamide is an effective therapeutic medicament for the treatment of endometriosis. Niclosamide treatment can reduce the size of endometrioid lesions and reduce cell proliferation in the lesions. Niclosamide treatment can result in the inhibition of proteins and genes associated with inflammatory signaling, including those associated with NFKB and STATS activation, but without altering the expression of steroid hormone receptors. Niclosamide can be effective in reducing the growth of endometrioid lesions in female mice without impairing their ability to become pregnant and without negative effect on gestation and offspring. The invention herein is useful in treating symptoms associated with endometriosis, such as reducing the growth of lesions of the endometrium, without disrupting normal reproductive function in females. The invention also relates to derivatives of niclosamide having improved solubility and enhanced efficacy.

The invention discloses self-doped conductive polyanilines and a method for preparing them. The benzene and/or quinone rings of these polyanilines bear functionalized grafts, or substituants, corresponding to the formula: -A-Z where A is a hydrocarbon radical having 2 to 8 atoms interrupted by at least one hetero-atom, Z is a strong acid function or one of its salts.
摘要:
The present invention relates to sulfonic acid containing compounds of formula IB, in which G, R 1 , R 3 and T are as defined in the claims, that bind to thyroid receptors in the liver. Activation of these receptors results in modulation of gene expression of genes regulated by thyroid hormones. The compounds can be used to treat diseases and disorders including metabolic diseases such as obesity, NASH, hypercholesterolemia and hyperlipidemia, as well as associated conditions such as atherosclerosis, coronary heart disease, impaired glucose tolerance, metabolic syndrome X and diabetes.
摘要:
Novel trans-1, 2-diphenylethylene derivatives are synthesized which can be used to form nanoparticles-monomer- nanomolecule-receptor nanosensors. These trans-1, 2-diphenyl- ethylene derivatives are soluble in both water and organic solvents, highly fluorescent and can be synthesized in high yields. The trans-1, 2-diphenylethylene derivatives are bonded to a nanoparticle, a nanomolecule bonded to the derivative and a receptor bonded to the nanomolecule to form a nanosensor that can be used to detect chemical and biological agents.
