摘要:
Disclosed herein are antiviral agents, pharmaceutical formulations comprising effective amounts of these agents and methods for treating mammals suffering from infections caused by viruses. The agents are analogs, isomers, homologs, derivatives and salts of aromatic polycyclic diones.
摘要:
Novel antiviral (including antiretroviral) compounds are mono- or dicarboxylic acid esters of hypericin in which one or both of the methyl groups of hypericin are substituted by carboxylic acid ester groups of the formula COOR3 in which R3 is alkyl, the chain of which is optionally interrupted by one or more oxygen or sulphur atoms. R3 is preferably methyl, ethyl, propyl, butyl, 2-methoxyethyl or 2-(2-methoxyethoxy)ethyl. The compounds may be formulated into pharmaceutical compositions and may be used in any manner which has previously been known for hypericin.
摘要:
A method for treating a papilloma virus infection comprising topically administering hypericin which is effective to inhibit the replication, growth and/or the infectivity of the virus. The papilloma viruses include those capable of causing benign warts or a malignancy such as human papilloma virus-1 (HPV-1), HPV-2, HPV-6, HPV-11, HPV-16 and HPV-18.
摘要:
The present invention provides compositions, articles and methods for inactivating viruses present in whole blood and other body fluids. The method comprises contacting the body fluids with an effective amount of an antiviral compound. Blood bags, vacuum blood tubes, condoms, spermicidal jellies and vaginal lubricants containing effective amounts of the antiviral compounds are also provided.

摘要:
Pharmaceutical formulations comprising aromatic polycyclic dione compounds useful for treating mammals suffering from diseases caused by retroviruses are disclosed herein. A method for treating mammals suffering from retrovirus infections is also disclosed.
摘要:
T cell-mediated diseases in mammals are treated using compositions comprising a polycyclic aromatic compound, preferably hypericin or pseudohypericin, and related compounds, including isomers, analogs, derivatives, salts, or ion pairs of hypericin or pseudohypericin. The above composition may be administered in combination with an immunosuppressive agent. Pharmaceutical compositions useful for treating a T cell-mediated disease comprise the above polycyclic aromatic compound, alone or in combination with an immunosuppressive agent. The compositions and methods are useful in treating diseases which include multiple sclerosis, myasthenia gravis, scleroderma, polymyositis, graft-versus-host disease, graft rejection, Graves disease, Addison's disease, autoimmune uveoretinitis, autoimmune thyroiditis, pemphigus vulgaris and rheumatoid arthritis. Psoriasis and systemic lups erythematosus. Also provided are methods for diminishing the expression of CD4 Molecules on the surface of a T lymphocyte, and for inducing multidrug resistance in a cell, comprising incubating the cell with an effective concentration of a polycyclic aromatic compound.
摘要:
The present invention relates to methods and compositions for treating tumors using vectors that preferentially target tumor cells. In particular, the invention relates to alphavirus-based, preferably Sindbis virus-based, vectors and to non-alphavirus-based vectors, which have a preferential affinity for high affinity laminin receptors (HALR). These vectors are efficiently targeted to tumors and have the ability to cause tumor necrosis.
摘要:
Disclosed herein are new defective Sindbis viral vectors made from wild type Ar-339 Sindbis virus, with differences in replicase and envelope proteins between JT vectors and consensus Sindbis virus sequences, and also between JT and Ar-339 vectors. Also disclosed are plasmids used for the production of the vectors, methods for producing the vectors, methods for treating mammals suffering from tumors and pharmaceutical formulations for use in the treatment methods.
摘要:
The invention concerns an improvement in the art of inserting and expressing foreign gene into eukaryotic cells. The invention particularly concerns methods and compositions whereby viral vectors can be used to insert and express foreign genes into specifically cells having particular differentiation antigens. A method of determining which differentiation antigens can be used is taught. The invention encompasses complexes of viral particles and adapters that cause the binding and internalization of the vector particles such that a gene of interest in the particle is expressed.
