The present invention relates to methods for treating cancer comprising utilizing a combination of signal transduction inhibitors. More specifically, the present invention relates to combinations of so called cell cycle inhibitors with mitogen stimulated kinase signal transduction inhibitors, more specifically combinations of CDK inhibitors with mitogen stimulated kinase signal transduction inhibitors, more preferably MEK inhibitors. Other embodiments of the invention relate to additional combinations of the aforesaid combinations with standard anti-cancer agents such as cytotoxic agents, palliatives and antiangiogenics. Most specifically this invention relates to combinations of 6-acetyl-8-cyclopentyl-5-methyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one including salt forms, which is a selective cyclin-dependent kinase 4 (CDK4) inhibitor, in combination with one or more MEK inhibitors, most preferably N-[(R)-2,3-dihydroxy-propoxy]-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The aforementioned combinations are useful for treating inflammation and cell proliferative diseases such as cancer and restenosis.

The present invention relates to the use of specific EGF-receptor antagonists for preparing a pharmaceutical composition for the prevention and/or treatment of benign prostatic hyperplasia and/or prostatic hypertrophy, a method for the treatment or prevention of benign prostatic hyperplasia/prostatic hypertrophy comprising administering an EGF-receptor antagonist of groups (A), (B) or (C), described herein optionally in combination with known compounds for the treatment of benign prostatic hyperplasia/prostatic hypertrophy, as well as associated pharmaceutical compositions.

Methods and reagents are provided for determining the activation state of a signal transduction pathway signaling protein. There exists a need in the art for methods that can monitor the efficacy of a signal transduction inhibitor in a patient. Other needs exist for detecting and monitoring certain disease or disorders that are associated with aberrant activation of a signal transduction pathway signaling protein. The present assay provides a highly sensitive assay that is also useful in patient populations in which obtaining a large cellular sample is difficult, for example, neonates.

The present invention relates to the use of specific EGF-receptor antagonists for preparing a pharmaceutical composition for the prevention and/or treatment of benign prostatic hyperplasia and/or prostatic hypertrophy, a method for the treatment or prevention of benign prostatic hyperplasia/prostatic hypertrophy comprising administering an EGF-receptor antagonist of groups (A), (B) or (C), described herein optionally in combination with known compounds for the treatment of benign prostatic hyperplasia/prostatic hypertrophy, as well as associated pharmaceutical compositions.

Stat3 inhibitor compounds are disclosed, wherein the compounds are structural analogs of Ac-pTyr-Leu-Pro-Gln-Thr-NH₂ and bind to the SH2 domain of Stat3 under physiological conditions to inhibit a cellular signaling activity of Stat3.

Novel pyrazolopyridine derivative compounds are disclosed and their use as pharmaceutical agents, in particular their use as TGF-beta signal transduction inhibitors useful in the treatment of cancer and other disease states influenced by TGF beta.

The invention provides a culture medium for culturing mammary epithelial stem cells. The culture medium contains a TGF-beta inhibitor, B27 and/or N2, insulin, a receptor tyrosine kinase ligand, a Rock kinase inhibitor, a P38 signal transduction inhibitor, a bone morphogenetic protein inhibitor and an MST1/2 kinase inhibitor. The invention also provides a method for culturing cells by adopting the culture medium for the mammary epithelial stem cells, and application and methods of amplified cell populations or organoids obtained by adopting the culture method in drug screening, toxicity testing and regenerative medicine.

Methods and pharmaceutical compositions for treating severe ischemic events including cerebral infarction, cardiac infarction, or pulmonary embolism, comprising a thrombolytic intervention including thrombolytic agents and an inhibitor of vascular endothelial growth factor (VEGF) receptor-mediated signal transduction are disclosed.

The invention provides improved compositions (e.g., combinations of signal transduction inhibitors) and methods for the prevention, stabilization, or treatment of cancer or other angiogenesis related diseases. In particular, the present methods use combination therapies to modulate the expression or activity of multiple mRNA molecules or proteins associated with angiogenesis or cancer in a mammal (e.g., a human)

An object of the present invention is to provide a method for inhibiting activation of signaling pathway mediated by erbB1 or erbB2 in human cell and a signaling inhibitor to be used therefor. The above-described activation of signaling pathway can be inhibited by a polypeptide comprising at least one of PTB domain or ERK2 binding domain of human FRS2β. The above-described polypeptide may be introduced directly into cell, or nucleic acid which encodes for the above-described polypeptide may be introduced into cell to allow expression of the polypeptide in the cell. Such polypeptide and nucleic acid can be used, for example, as a signaling inhibitor. In addition, since erbB1 and erbB2 are involved in development of cancer, the above-described signaling inhibitor is also useful, for example, as an anticancer drug.

Provided herein are methods of treating beta-thalassemia by subcutaneous administration of about 0.8 mg/kg of an ActRII signaling inhibitor. Also provided herein are methods of adjusting the dose of the ActRII signaling inhibitor administered to the subject.

A method of treating an individual comprising: evaluating the disease state of said individual through quantitative and/or qualitative assays; administering in amounts sufficient to treat said disease at least three agents wherein at least one agent is an inhibitor of the human epidermal receptor pathway, at least one agent is signal transduction inhibitor and at least one agent is an angiogenesis inhibitor and; reevaluating the disease state of said individual presenting through quantitative and/or qualitative assays. A composition comprising a first agent that is an inhibitor of the human epidermal receptor pathway, a second agent that is an angiogenesis inhibitor and a third agent that is an inhibitor of Akt wherein said first agent, second agent, third agent and combinations thereof are present in amounts that when administered to an individual in a diseased state are sufficient to treat said disease.

The present invention relates to a composition comprising at least one biological control agent. Furthermore, the present invention relates to the use of this composition as well as a method for reducing overall damage of plants and plant parts.

The invention relates to a new application of phenothiazine compounds in pharmacy, wherein the phenothiazine compounds are selected from a compound represented by a formula (I), hydrates, solvates orreduced forms thereof; the invention particularly provides the application in preparation of a PD-1 signal transduction inhibitor. The phenothiazine compounds provided by the invention can inhibit thefunction of PD-1 and hinders the signal transduction of PD-1, so that the phenothiazine compounds can be used as a PD-1 signal transduction inhibitor. In-vitro experiments find that the compounds canrecover the functions of immune cells inhibited by PD-1, so that the functions of secreting cytokines and killing target cells of immune cells such as CTL and the like are improved, the immune function of an organism can be improved, and tumors can be effectively treated.
