This invention relates to compounds that are useful as cancer therapies. The compounds comprise derivatives of tetracycline antibiotics, e.g. doxycycline, having a phosphonium cation tethered to the tetracycline tetracycle. The invention also relates to methods of using said compounds and to pharmaceutical formulations comprising said compounds.

Disclosed are chemical entities which are compounds of formula (I):

##STR00001##

or pharmaceutically acceptable salts thereof; wherein Y, R.sup.a, R.sup.a, R.sup.b, R.sup.c, X.sub.1, X.sub.2, X.sub.3, R.sup.d, Z.sub.1, and Z.sub.2 have the values described herein and stereochemical configurations depicted at asterisked positions indicate absolute stereochemistry. Chemical entities according to the disclosure can be useful as inhibitors of Sumo Activating Enzyme (SAE). Further provided are pharmaceutical compositions comprising a compound of the disclosure and methods of using the compositions in the treatment of proliferative, inflammatory, cardiovascular, and neurodegenerative diseases or disorders.

The present invention relates to compounds of general formula (I) in particular for use in the treatment of senescence-related diseases, such as idiopathic pulmonary fibrosis, sarcopenia, diabetes, obesity, osteoarthritis, chronic inflammations, glaucoma, cataracts, radiation-induced oral mucosis, renal transplantation, prostatic hyperplasia.

The deferoxamine derivatives of general formula I and pharmaceutically acceptable salts thereof, at least one of R1 and R2 is a substituent of formula II. The novel derivatives are particularly suitable as medicaments, preferably for the treatment of cancer. Pharmaceutical preparations of compounds of formula I and a metal, preferably gallium, are also provided resulting in even more active medicaments or contrast agents. Combinations with other agents, resulting in synergistic effects are provided.

The present invention relates to the use of silver(I) monophosphine complexes as Active Pharmaceutical Ingredients (API's), including anticancer agents, for the treatment, diagnosis and/or prevention of cancer. The present invention also relates to pharmaceutical compositions containing such complexes and further extends to a method of treating or diagnosing a subject/patient suffering from cancer.

Therapeutically-effective amounts of novel analogs or derivatives of alkyl fatty acids, such as but not limited to lipoic acid, and pharmaceutical formulations comprising such analogs or derivatives and pharmaceutically-acceptable carriers therefor, are useful for the treatment, prevention, imaging, and/or diagnosis of medical disorders.

1,7-diaryl-1,6-heptadiene-3,5-dione derivatives, methods for the production and use thereof.

Provided are an inhibitor for RuO.sub.4 gas generation used in a manufacturing process of a semiconductor element, that inhibits a RuO.sub.4 gas generated when a semiconductor wafer containing ruthenium and a treatment liquid are brought into contact, and a method for inhibiting the RuO.sub.4 gas. Specifically, provided is an inhibitor for RuO.sub.4 gas generation for inhibiting a RuO.sub.4 gas generated when a semiconductor wafer containing ruthenium and a treatment liquid are brought into contact in semiconductor formation steps, wherein the inhibitor includes an onium salt consisting of an onium ion and a bromine-containing ion. Also provided is a method for inhibiting RuO.sub.4 gas generation by adding the inhibitor to a ruthenium treatment liquid or a ruthenium-containing liquid used in semiconductor formation steps.

The present approach effectively eradicates senescent cells and cells carrying the hallmarks associated with aging, through inhibiting mitochondrial biogenesis during induced mitochondrial oxidative stress, without inhibiting normal cells. Embodiments may include a therapeutic agent that inhibits mitochondrial biogenesis and targets the large mitochondrial ribosome, a therapeutic agent that inhibits mitochondrial biogenesis and targets the small mitochondrial ribosome, and a therapeutic agent that behaves as a pro-oxidant or induces mitochondrial oxidative stress. Some embodiments include sub-antimicrobial antibiotic concentrations, thereby minimizing antibiotic resistance concerns.

The present invention provides mito-honokiol or mito-magnolol compounds, pharmaceutical compositions thereof, and methods of using the mito-honokiol or mito-magnolol compounds in the treatment of cancer.
