A method of improving the endogenous production of prostaglandins by a mammal is disclosed, which comprises administering to the mammal an effective amount of 1-pyridylalkyl-3-naphthyl-2(thio)ureas. Disclosed also are novel substituted 1-pyridylalkyl-3-naphthyl-2(thio)ureas and therapeutic compositions thereof which are useful in carrying out the method of the invention. Disclosed also are methods of treating mammals for clinical conditions responsive to prostaglandins, such as, for example, male infertility, epidermal injuries, atonic uterine bleeding, thromboembolic disease and like clinical conditions.

comparison with the parent urea or thiourea derivatives are presented. The naphthalenederivatives showed characteristic emissions, among which the nitrate salt of naphurea showed dual emissions at 386 and 509 nm upon excitation at 335 nm. We have taken the advantage of the emissive behaviour of these compounds to deliberate the comparative release of urea derivatives from composites of calcium oxide impregnated
