There are provided according to the invention novel compounds of formula (I) or pharmaceutically acceptable salts thereof, wherein R1, R2, R19, R20 and R34 are as described in the specification, processes for preparing them, formulations containing them and their use in therapy for the treatment of inflammatory diseases.
A compound of formula (I) or a pharmaceutically acceptable salt or prodrug thereof: wherein R1 is CN; R2 is H or F; R3 and R4 are independently hydrogen, fluorine, chlorine or OR8; R5 is hydrogen, C1-6 alkyl, C1-6 alkenyl or C1-6 alkynyl; R6 and R7 are independently hydrogen, halogen, OR8 or NR9R10; R8 is hydrogen or C1-6 alkyl; R9 and R10 are independently hydrogen or C1-6 alkyl; or the groups R9 and R10 when they are attached to a nitrogen atom may together form a 5- or 6-membered ring which optionally contains one further heteroatom selected from NR8, S and O said 5 or 6 membered ring being optionally substituted by hydroxyl or C1-6 alkoxy; or the groups R9 and R10 when they are attached to a nitrogen atom may together form an azetidinyl ring optionally substituted by hydroxyl or C1-6 alkoxy, is provided. The use of such compounds in treating amyloid-related disease is also disclosed.

vitro. Four ligands displayed affinities that are similar or superior to those of the promising SPECT radioligand ([123I]CNS1261). The 3′-dimethylamino (19; Ki 36.7 nM), 3′-trifluoromethyl (20; Ki 18.3 nM) and 3′-methylthio (2; Ki 39.8 nM) derivatives of N-1-naphthyl-N′-(phenyl)-N′-methylguanidine were identified as especially attractive leads for PET radioligand development.

The invention relates to radioprotectors of formula (I), processes for their preparation and their use in protecting biological materials from radiation damage. In diagnostic and therapeutic radiology, particularly in cancer radiotherapy, the radioprotectors of the present invention may be used to protect certain normal tissues or structures from radiation damage. The radioprotectors of formula (I) may also have uses in decreasing the effects of irradiation in non-medical scenarios, both civil and military.
