摘要:
The invention provides compounds of formula (I): wherein A and B represent the groups —(CH2)m— and —(CH2)n— respectively; R1 represents hydrogen or C1-6alkyl; R2 represents hydrogen, halogen, hydroxy, cyano, nitro, hydroxyC1-6alkyl, trifluoromethyl, trifluoromethoxy, C1-6alkyl, C1-6alkoxy, C1-6fluoroalkoxy, —(CH2)pC3-6cycloalkyl, —(CH2)pOC3-6cycloalkyl, —COC1-6alkyl, —SO2C1-6alkyl, —SOC1-6alkyl, —S—C1-6alkyl, —CO2C1-6alkyl, —CO2NR3R4, —SO2NR3R4, —(CH2)pNR3R4, —(CH2)pNR3COR4, optionally substituted aryl ring, optionally substituted heteroaryl ring, a fused bicyclic heteroaromatic ring system or optionally substituted heterocyclyl ring; Ar1 represents optionally substituted heteroaryl ring; Ar2 represents optionally substituted aryl ring or optionally substituted heteroaryl ring; Z represents —(CH2)qX— wherein the —(CH2)q— group is attached to Ar2, or —X(CH2)q— wherein X is attached to Ar2, and wherein any of the —CH2— groups may be optionally substituted by one or more C1-6alkyl groups; X represents oxygen, —CH(OR5)—, —NR5— or —CH2— wherein the —CH2— group may be optionally substituted by one or more C1-6alkyl groups; R3 and R4 each independently represent hydrogen, C1-6alkyl or, together with the nitrogen or other atoms to which they are attached, form an azacycloalkyl ring or an oxo-substituted azacycloalkyl ring; R5 represents hydrogen or C1-6alkyl; m and n independently represent an integer selected from 1 and 2; p independently represents an integer selected from 0, 1, 2 and 3; q independently represents an integer selected from 0, 1, 2 and 3; or a pharmaceutically acceptable salt or solvate thereof, with the proviso that when Ar1 is a pyridyl group, and Z is —CH2X— where X is attached to the Ar1 group, X is selected from —CH(OR5)—, —NR5— and —CH2— wherein the —CH2— group may be optionally substituted by one or more C1-6alkyl groups. The compounds of formula (I) are useful in therapy, in particular as antipsychotic agents.

The present invention discloses a portable, collapsible clipboard which may be mounted to a vehicle steering wheel by means of an elastic strap or removed and carried by means of a provided shoulder strap. The clipboard is comprised of two writing portions that are hingedly connected so that the clipboard can be folded in half or expanded to provide a larger writing surface. A latch is provided to keep the clipboard securely folded.

The present invention relates to naturally-occuring growth hormone mutations; to a method for detecting them and their use in screening patients for growth hormone irregularities or for producing variant proteins suitable for treating such irregularities. In one aspect there is disclosed a detection method for detecting a variation in GH1 effective to act as an indicator of GH dysfunction in an individual, which detection method comprises the steps of: (a) obtaining a test sample comprising a nucleotide sequence of the human GH1 gene from the individual; and (b) comparing the sequence obtained from the test sample with the standard sequence known to be that of the human GH1 gene, wherein a difference between the test sample sequence and the standard sequence indicates the presence of a variation (hereinafter “variant of GH1”) effective to act as an indicator of GH1 dysfunction characterised in that the test sample is obtained from an individual, either or both: exhibiting intra-uterine growth retardation (IUGR), defined as sufficient foetal height velocity diagnosed by standard methods known in the art; and/or small for gestational age (SGA), defined as insufficient (small) foetal body size (weight and/or length) for gestional age diagnosed by standard methods known in the art.
摘要:
A link controller for use in a node of a network includes a digital controller (102) that employs a knowledge-based control program (103). The device and method provide flexible master node designation, automatic installation, configuration and reconfiguration, and recognition and correction of network communication problems resulting from interference and other adverse conditions. The knowledge-based control program (103) employs an inference engine and a set of rules to dynamically optimize network configuration. Multipath is managed by locking on to reflected signals when a direct signal is unavailable. Operation is transparent to network users.

The window shade lock device includes a handle having a round or elongated hand grip end and a slide connector extending forwardly thereof. The slide connector is pivotally secured, preferably off center, to the preferably generally rectangular body of a slide bearing four spaced, axled, rotatable wheels, two on each of two opposite sides thereof. The wheels are adapted to ride in parallel spaced channels in a window shade side frame. The wheels extend beyond the side margins of the slide body. The slide body extends out of the frame into connection with the connector front end outside the frame. The handle is pivotally movable up and down between a locked and unlocked position. When in the locked position the slide connector front end biases the slide, specifically the wheels thereof, tightly against the frame to hold the lock in position. In the unlocked position the slide connector front end biases and spaces the slide from the frame for free movement therein. Locking of the handle to the frame also locks a window shade secured at its lower end to the handle and/or slide by a shade connector in the form of a flexible or rigid strut or the like. The device is compact, simple and efficient.

A novel anthracycline antibiotic complex, fragilomycin complex, is produced by the cultivation of a fermentation broth containing Streptosporangium fragile Shearer sp. nov. ATCC 31519 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The fragilomycin complex and its major bioactive component, fragilomycin A, exhibit antibiotic activity.
