The present invention provides novel dithiolopyrrolone compounds and their salts, which are useful as treatments for cancer and other proliferative diseases. The present invention also provides therapeutic compositions comprising particularly useful types of dithiolopyrrolones, the salts thereof, and methods of using the compounds within such types, particularly in treating proliferative diseases such as cancer.

Dithiolopyrrolones with therapeutic activity

The invention provides novel 1,2-diphenylethene derivatives and pharmaceutically acceptable salts thereof, the process for production of these compounds and their pharmaceutical composition and the use of these compounds as modulators of T-cells, neutrophils, macrophages and their associated cytokines as agents for treating immune, inflammatory and auto-immune diseases.

1,2-diphenylethene derivatives for treatment of immune diseases

The invention is drawn to novel macrolide compounds of formula I having antibiotic and antineoplastic activities, useful as medicaments and/or agrochemicals for microorganism infections, in particularly for infectious diseases involving drug-resistant, and for treatment of human and animal cancers. 

Macrolide compounds with antibiotic and antineoplastic properties

The present invention provides novel methods of treating psoriasis, protein tyrosine kinase-associated disorders, inflammation, epidermal hyperproliferation, diabetes, immune and autoimmune diseases, eczema, and inflammatory bowel disease, inhibiting protein kinase, neutrophil activation, cell proliferation, tumour growth, metastasis, and the development of atheromatous plaque and restonosis, controlling angiogenesis, and preventing inflammatory bowel disease, using hydroxystilbenes and novel stilbene derivatives.

Anti-inflammatory and psoriasis treatment and protein kinase inhibition by hydroxy stilbenes and novel stilbene derivatives and analogues

The present invention provides novel diphenyl ethene compounds and pharmaceutically-acceptable salts thereof. Also provided are methods for making the compounds of the invention as well as methods for the use thereof in the treatment of immune, inflammatory, and auto-immune diseases.

Compounds, isolated from the bacteria , have antineoplastic activity. The invention provides pharmaceutical compositions containing the compounds and the methods for employing them as medicaments, particularly in the treatment of human and animal cancers.

Antineoplastic agents
