    摘要: Neuroprotective drugs are disclosed with at least 3 branches extending outwardly from a center atom or group, each branch having a guanidino group at its terminus. All branches preferably should be identical, and distributed around the center atom or group in a radial manner. Three branches can be bonded to a nitrogen atom, or four branches can be coupled to a carbon atom; other center groups include stable aromatic, cycloalkyl, heterocyclic, or bicyclic structures. Starting reagents are disclosed with a center atom or group, and with reactive groups (such as primary amines or hydroxyl groups) at the ends of short "spacer chains" bonded to the center atom or group. Reagents derived from arginine (an amino acid having a terminal guanidino group) can be bonded to these center components, using protective groups on the arginyl reagents to ensure desired final products with accessible guanidino groups at the ends of spacer chains. Alternately, guanylating agents can be used to directly convert primary amine groups at the ends of spacer chains, on starting reagents, into guanidino groups. These drugs can be injected intravenously into patients suffering from ischemic or hypoxic crises (stroke, cardiac arrest, loss of blood, suffocation, etc.), and can penetrate the blood-brain barrier and suppress the entry of calcium into CNS neurons via N-type and P/Q-type calcium channels, thereby reducing excitotoxic damage in the CNS. These drugs are also useful for suppressing other types of unwanted excessive neuronal activation, such as neuropathic pain.

    摘要: The invention provides a compound, useful as an optical probe or sensor of the activity of at least one cytochrome P450 enzyme, and methods of using the compound to screen candidate drugs, and candidate drugs identified by these methods. The optical probe of the invention is a compound having the generic structure Y-L-Q, wherein Y is selected from the group consisting of Q as herein defined, saturated C1-C20 alkyl, unsaturated C1-C20 alkenyl, unsaturated C1-C20 alkynyl, substituted saturated C1-C20 alkyl, substituted unsaturated C1-C20 alkenyl, substituted unsaturated C1-C20 alkynyl, C1-C20 cycloalkyl, C1-C20 cycloalkenyl, substituted saturated C1-C20 cycloalkyl, substituted unsaturated C1-C20 cycloalkenyl, aryl, substituted aryl, heteroaryl and substituted heteroaryl; L is selected from the group of (—OCR2H)p—, wherein for each p, all R2 are separately selected from the group consisting of a hydrogen atom, saturated C1-C20 alkyl, unsaturated C1-C20 alkenyl, unsaturated C1-C20 alkynyl, substituted saturated C1-C20 alkyl, substituted unsaturated C1-C20 alkenyl, substituted unsaturated C1-C20 alkynyl, C1-C20 cycloalkyl, C1-C20 cycloalkenyl, substituted saturated C1-C20 cycloalkyl, substituted unsaturated C1-C20 cycloalkenyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, and p is a positive integer no greater than twelve; and Q is a chemical moiety that gives rise to optical properties in its hydroxy or hydroxylate, phenol or phenoxide form that are different from the optical properties that arise from its ether form. Most preferably, p is one, R2 is hydrogen, and Q is the ether form of a phenoxide fluorophore.
