Compounds which are 2-ureido-1,3-thiazole derivatives of formula (I) wherein R is a halogen atom, a nitro group, an optionally substituted amino group or it is a group, optionally further substituted, selected from: i) straight or branched C1-C6 alkyl; ii) C3-C6 cycloalkyl; iii) aryl or arylalkyl with from 1 to 6 carbon atoms within the straight or branched alkyl chain; R1 is an optionally substituted group selected from: i) straight or branched C1-C6 alkyl; ii) 3 to 6 membered carbocycle or 5 to 7 membered heterocycle ring, iii) aryl or arylcarbonyl; iv) arylalkyl with from 1 to 6 carbon atoms within the straight or branched alkyl chain: R2 is hydrogen, a straight or branched C1-C4 alkyl or C2-C4 alkenyl or alkynyl group; or, taken together with the nitrogen atom to which they are bonded, R1 and R2 form a substituted or unsubstituted group selected from: i) an optionally benzocondensed or bridged 5 to 7 membered heterocycle; or ii) a 9 to 11 membered spiro-heterocyclic compound; or a pharmaceutically acceptable salt thereof; are useful for treating cell proliferative disorders associated with an altered cell dependent kinase activity.
