Granted: 2010-05-18
Abstract: The present invention provides a series of novel bifunctional molecules based on viologen linked acridine, bisacridine and bisacridinium salts of the general formula 1(1a,Ib, 1c and 1d) (see Formula II) la wherein Y = -(CH2)n- wherein n = 1-11 R = -MV2+ -(CH2)m-CH3 2X~ or -Pyr2+ -(CH2)m-CH3 2X~ wherein m = 1-13 1b wherein Y = -(CH2)n- wherein n = 1-11 R = -MV2- -(CH2)m-Acr 2X~ or -Pyr2+ -(CH2)m-Acr 2X~ wherein m = 1-11 1c wherein Y = ortho or para tolyl R = -MV2+ -(CH2)m-CH3 2X~ or -Pyr2+ -(CH2)m-CH3 2X~ wherein m = 1-13 1d wherein Y = -(CH2)n- wherein n = 5 or 10 R = -Acr+ -R1 X~/2X~ wherein N in the acridine main ring is also quarternised by alkyl group R1 = -(CH2)m-CH3 and -(CH2)m-C6H4-(CH2)m- (para), wherein m = 0-13 (see formula I) and or pharmaceutically acceptable derivatives thereof, which can be used as phototherapeutic and catalytic photoactivated DNA cleaving agents. These molecules are very stable and exhibit high solubility in buffer at physiological conditions. They undergo strong binding with DNA through intercalation and groove binding interactions and show remarkably high affinity for poly(dA).poly(dT) sequences. Upon photoactivation, they cleave DNA catalytically and selectively at guanine (G) sites in duplex DNA exclusively through cosensitization mechanism with a preference for 5'-G over 3'-G. They induce unusally high specificity of cleavage at G site of the AG two base bulge sequences. Accordingly, the viologen linked acridine based molecules described herein are extremely useful as probes for DNA structures and catalytic photoactivated DNA cleaving agents in biological applications.

Abstract: Apparatus (10) and a method for rendering a weapon (12) incapable of use unless authorized by a specified individual. More than one person may be authorized to use the weapon, however only one person may be authorized to use it at any one time. Each authorized person carries a badge (14) or other device which includes an rf transmitter (TAU) capable of transmitting a coded signal to a receiver (REU) installed in the weapon in response to a coded query from a unit (EU) installed in the weapon. If a properly coded transmission is received by the weapon, it becomes capable of being fired by the person who authorized its use. However, the weapon will not fire unless the person using the weapon is also standing behind the weapon. This prevents the weapon from being turned on the person authorized to use it. The apparatus stores details of the weapon's use (e.g., who, when, and where). This information is released upon receipt of an authorized code.
