标 题:Molecular Design and Chemical Synthesis of Pharmaceutical-Ligands and Pharmaceutical-Pharmaceutical Analogs with Multiple Mechanisms of Action

摘要:Multi-phase and single-phase chemical reaction schemes have been developed for the synthesis of pharmaceutical-ligand analogs, pharmaceutical-pharmaceutical analogs, and similar molecular-molecular analogs that possess multiple mechanisms of action. The multi-phase organic chemical reaction schemes include relatively mild reaction conditions, high end product yields, and comparatively rapid completion of chemical reactions, which are all of particular utility for the synthesis of preparations including covalent pharmaceutical-receptor ligand or pharmaceutical-immunoglobulin analogs. Examples of pharmaceutical-ligand preparations that can be synthesized utilizing the multi-step chemical reaction schemes include covalent chemotherapeutic-ligand agents that possess selective targeted delivery properties and a capacity to exert additive and synergistic levels of cytotoxic anti-neoplastic potency. Pharmaceutical-pharmaceutical analogs, including chemotherapeutic-chemotherapeutic analogs that are capable of exerting multiple mechanisms of action, can be synthesized using either of the described multi-phase or single-phase organic chemistry reaction schemes. Each of these representative examples has utility against a spectrum of disease states including, for example, neoplastic conditions such as mammary adenocarcinoma/carcinoma, ovarian carcinoma, prostatic carcinoma, intestinal carcinoma, melanoma, leukemia, myeloma, and lymphoma.

摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.

摘要:The invention provides synthetic methods for the preparation of cantharidin and analogs thereof. In one aspect, the invention provides an improved Diels-Alder cycloaddition to generate a key intermediate en route to cantharidin and analogs thereof. In certain embodiments, the new Diels-Alder reaction involves reacting Compound (2) in the presence of furan, and in the absence of acid or increased pressure, in an aprotic polar solvent with slight warming, to yield Compound (1) in favorable yield and exo-endo ratio. In another aspect, the invention also provides a new Diels-Alder reaction between compounds of Formula (III) and furan to yield compounds of Formula (IV), which can then be transformed into cantharidin or analogs thereof. In yet another aspect, the invention describes a new palladium-mediated carbonylation providing another key intermediate en route to cantharidin and analogs thereof. In addition to synthetic methods, present invention also provides compounds (i.e., intermediates) useful in the synthesis of cantharidin and analogs thereof. Compounds provided herein may have biological activity, and therefore may be used in the treatment of diseases or conditions (e.g., infectious diseases and skin conditions).

摘要:Methods for the treatment of patients with both Chronic Obstructive Pulmonary Disease (COPD) and pulmonary fibrosis, and of patients with idiopathic pulmonary fibrosis without COPD, by stimulating the synthesis of human and animal patient lung and sinus surfactants to increase lung functions, inhibiting fibrosis and reducing coughing and nasal erythema, include the following steps: A) analyzing and diagnosing a patient with a lung ailment selected from the group consisting of i) both COPD and pulmonary fibrosis; and ii) idiopathic pulmonary fibrosis without COPD; and, B) treating the patient to raise the patient's lung functions including FEV1/FVC ratio by contacting mammalian cells with a [therapeutically effective amount of a treatment] composition that includes: a) a pyruvate salt; b) a phosphate; c) a salt of calcium; and d) a salt of magnesium, in an aqueous carrier, containing no more than 2.2 grams of said pyruvate salt per liter.
