New Substituted 1,4-Benzoxazine Derivatives with Potential Intracellular Calcium Activity
摘要:
Substituted 1,4-benzoxazines bearing an amino side chain at the 2-position were prepared and were found to have a moderate activity on intracellular calcium. Of the compounds studied it was found that those which possess a homoveratrylamino moiety exhibited superior potency. The chain length and the nature of the amine (4-fluorophenylpiperazine, 4-fluorobenzhydryloxyethylamine, N-substituted homoveratrylamine) is discussed. The 4-benzyl-3,4-dihydro-2[3-[[2-(3,4-dimethoxyphenyl)ethyl]amino]propyl]-2H-1,4-benzoxazine (3c) is the most potent derivative of the series with a ratio of IC50 values against PE (phenylephrine) and K+ of 2.1. Under these test conditions a ratio near 1 indicates potential intracellular calcium activity while a ratio greater than 100 an action on extracellular calcium influx.

The present invention features compounds active at both the serotonin reuptake site and the N-methyl-D-aspartate (NMDA) receptor and the use of such compounds for treating different disorders. Compounds having activity at the serotonin reuptake site and the NMDA receptor ("multi-active compounds") can be used to treat different types of disorders such as obsessive-compulsive disorders (OCD), sleep disorders, sexual dysfunction, and eating disorders.
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said agent being capable of forming at least two types of binding pairs with a target.
Diphenylmethoxyethylamines of the general formula ##STR1## in which R.sub.1 represents a fluorine, bromine or chlorine atom, R.sub.2 represents a hydrogen or fluorine atom and R.sub.3 represents a hydrogen, fluorine or chlorine atom, with the provisos that R.sub.3 is a hydrogen atom when R.sub.2 is a fluorine atom, R.sub.1 is a fluorine atom when R.sub.3 is a chlorine atom and R.sub.1 is a fluorine or bromine atom when R.sub.2 and R.sub.3 both are hydrogen atoms, and their non-toxic acid addition salts are disclosed. The compounds have dopaminergic properties and their use is indicated for treating the Parkinson syndrome. Compositions for such use are disclosed.

The present disclosure provides a once-daily water-soluble pharmaceutically active formulation for oral administration. In certain embodiments, the composition comprises a water-soluble pharmaceutically active organic compound incorporated into a small particulate, each particulate having a core of the water-soluble pharmaceutically active organic compound or an acceptable salt thereof in reversible association with a pharmaceutically acceptable drug-binding polymer. The core of the composition being surrounded by an insoluble water permeable membrane that is capable of delaying the dissolution of the pharmaceutically active compound therewithin and providing for extended release of the pharmaceutically active compound. In some embodiments, the formulation of the invention are designed to extend release of the pharmaceutically active organic compound for about 3 hours to about 8 hours, thereby enabling preparation of an extended release formulation for any pharmaceutically active compound with a half-life of from about 16 hours to about 21 hours.

The synthesis of a series of diphenylalkylamine derivatives related to prenylamine is reported. The amphetamine group in the prenylamine structure was replaced by other moieties. In addition to substitutions in the aromatic rings, heteroatoms such as sulphur and oxygen were introduced in the chain. The calcium-entry blocking activity was assayed in binding experiments on a guinea-pig brain membrane preparation by displacing [H-3]-nitrendipine.
