摘要:
The present invention relates to methods for the treatment of metastatic cancer. Methods of treating metastatic cancer by administration of a set of drugs overcome multiple mechanisms of melphalan resistance and hypersensitize cancer cells to melphalan are described. The methods involve the administration of drug(s) that induce oxidative stress in cancer cells, in conjunction with melphalan on a defined schedule.

The present invention provides compositions, methods for lyophilizing compounds and making pharmaceutical compositions, and kits providing solutions and lyophilized formulations of compounds. The compositions, methods, and kits are particularly useful in pharmaceutical applications involving therapeutic agents that have low solubility at low pH and medium pll values. Certain embodiments provide methods for lyophilizing compounds in liquid solutions, which include the steps of: a) preparing aqueous solutions of a compound of interest in the absence of buffer; b) adjusting the pH to high values of pH in order to increase the solubility of the compound of interest; and c) frecze-drying the solution to provide a lyophilized solid composition. Aqueous solutions including buffer are also disclosed. Lyophilized formulations, including micronized and non-micronized powders, are provided.

Non ligand binding pocket antagonists for the human androgen receptor. The androgen receptor (AR) is a member of the Nuclear Receptor (NR) family and its role is to modulate the biological effects of the endogenous androgens, testosterone (tes) and dihydrotestosterone (DHT). Synthetic androgens and anti-androgens have therapeutic value in the treatment of various androgen dependent conditions, from regulation of male fertility to prostate cancer. Current treatment of prostate cancer (PCa) typically involves administration of 'classical' antiandrogens, competitive inhibitors of natural AR ligands, DHT and tes, for the ligand binding pocket (LBP) in the C-terminal ligand binding domain (LBD) of the AR. However, prolonged LBP-targeting can often lead to androgen resistance and alternative therapies and therapeutic strategies are urgently required. Disclosed herein are a class of non-steroidal, small molecule AR antagonists which inhibit the transcriptional activity of the AR by non LBP-mediated modulation. The novel class reported demonstrates full ('true') antagonism in AR with low micromolar potency, high selectivity over both the Estrogen Receptors alpha and beta (ERα and ERβ) and the Glucocorticoid Receptor (GR) and only micromolar partial antagonism in the Progesterone Receptor (PR). Data provide compelling evidence for such non-LBP intervention as an alternative approach to classical PCa therapy. (Formula I).

Enteric compositions comprising one or more tight junction agonists and/or one or more tight junction antagonists are provided. Compositions of the invention may comprise a delayed-release coating disposed over a tight junction agonist and/or tight junction antagonist layer which may be disposed over an inert core. Delayed-release coatings may be substantially stable in gastric fluid and substantially unstable in intestinal fluid, thus providing for substantial release of the tight junction agonist and/or antagonist from the composition in the duodenum or jejunum of the small intestine.

The invention is in the field of disorders of glucose homeostasis therapy. In particular the invention relates to a CFTR inhibitor or an inhibitor of CFTR gene expression for use in the treatment of disorders of glucose homeostasis. The present invention also relates to an in vitro methods for increasing the pool of Ngn3+ endocrine progenitor cells, pancreatic endocrine cells, or β cell mass obtained from stem cells, wherein said methods comprises the step of contacting stem cells with a CFTR inhibitor or an inhibitor of CFTR gene expression. The present invention also relates to a method of testing a subject thought to have or be predisposed to having disorders of glucose homeostasis, which comprises the step of analyzing a sample of interest from said subject for: (i) detecting the presence of a mutation in the CFTR gene and/or its associated promoter, and/or (ii) analyzing the expression of the CFTR gene.
