摘要:
The present invention provides compounds that act as selective agents to protect against unintentional cell death or tissue damage and can relieve side effects of cancer treatment such as, for example, oral mucositis, hair loss, diarrhea due to damage to the gastrointestinal epithelium, and myelosuppression. In addition, these compounds can be used to prevent premature cell death when the cell death is caused by signals from damaged cells, for example, signals generated as the result of a traumatic incident or an ischemic episode.

摘要:
The present invention provides a therapeutic method to treat non-malignant diseases characterized by the excessive tissue growth, e.g., hyperplastic diseases, comprising administering to a mammal (e.g., human) afflicted with excessive tissue growth, an effective amount of a derivative of an indole compound of formula (I):formula (I): wherein R1 is lower alkyl, (hydroxy)lower alkyl, lower alkenyl, lower alkynyl, lower cycloalkyl, phenyl, benzyl or 2-thienyl; R2, R3, R4 and R5 are the same or different and are each hydrogen or lower alkyl; each R6 is individually hydrogen, lower alkyl, hydroxy, (hydroxy)lower alkyl, lower alkoxy, benzyloxy, lower alkanoyloxy, nitro or halo, R7 is hydrogen, lower alkyl or lower alkenyl, X is oxy and thio, Y is carbonyl, —(CH2)1-3—, —(C1-C3)alkyl(CO)—, or —(CH2)1-3SO2—; Z is hydroxy, lower alkoxy, (C2-C4)acyloxy, —N(R8)(R9), phenylamino, (ω-(4-pyridyl)(C2-C4 alkoxy), (ω-((R8)(R9)amino)(C2-C4 alkoxy), an amino acid ester of (ω-(HO)(C2-C4))alkoxy, —N(R8)CH(R8)CO2H, 1′-D-glucuronyloxy, —SO3H, —PO4H2, —N(NO)(OH), —SO2NH2, —PO(OH)(NH2), —OCH2CH2N(CH3)3+, or tetrazolyl; wherein R8 and R9 are each H, (C1-C3)alkyl or together with N are a 5- or 6-membered heterocyclic ring comprising 1-3 N(R8), S or nonperoxide O; n is 0, 1, 2, or 3; wherein R8 and R9 are each H, (C1-C3)alkyl or together with N are a 5- or 6-membered heterocyclic ring comprising 1-3 N(R8), S or nonperoxide O; each alkyl or phenyl group of R1, R2, R3, R4, R5, R6, R7 and Z is optionally substituted with 1, 2, or 3 (C1-C4)alkyl groups; or a pharmaceutically acceptable salt thereof.
摘要:
The present invention provides for TLR agonist conjugates (compounds) and compositions, as well as methods of using them. The compounds of the invention are broad-spectrum, long-lasting, and non-toxic combination of synthetic immunostimulatory agents, which are useful for activating the immune system of a mammal, preferably a human and can help direct the pharmacophore to the receptor within the endosomes of target cells and enhance the signal transduction induced by the pharmacophore.
摘要:
The present invention provides compounds that act to suppress p53 activity in mammalian cells, and a method to effectively suppress p53 activity in the cells of a mammal subject to a stress or pathology that is ameliorated by such suppression.
摘要:
The present invention provides novel indole derivatives useful to inhibit cancer or sensitize cancer cells to chemotherapeutic agents, radiation or other anti-cancer treatments.
摘要:
An in vivo method for depleting mammalian cells of adenosine 5′-monophosphate (AMP) useful in the treatment of certain cancers is provided. According to the method, a population of cells is obtained from a host and assayed for loss of methylthioadenosine phosphorylase (MTAse) activity. MTAse catabolizes methylthioadenosine to adenine for endogenous salvage incorporation into the intracellular AMP pool. The preferred method for assaying loss of MTAse activity is a hybridization technique for detection of a homozygous loss of the gene which encodes MTAse. Hosts having MTAse deficient tumors are treated with a therapeutically effective amount of an agent which inhibits the activity of adenylsuccinate synthetase, which converts inosine 5-monophosphate to AMP, thus depleting the tumor cells of substrates for de novo AMP production. L-alanosine is the preferred ASS inhibitory agent for use in the method of the invention.
