  • Patent number: RE47388
    Abstract: The present invention provides an agent for alleviating side effects caused by use of an anti-tumor agent, which contains 5-chloro-6-(2-iminopyrrolidin-1-yl)methyl-2,4(1H,3H-pyrimidi nedione (1) represented by formula (1): or a pharmaceutically acceptable salt thereof. The 5-chloro-6-(2-iminopyrrolidin-1-yl)methyl-2,4(1H,3H)-pyrimidinedione or a pharmaceutically acceptable salt thereof exhibit an inflammatory-suppressing action in the digestive tract and advantageously alleviate diarrhea and loss of body weight concomitant with administration of a chemical for treating cancer without suppressing the anti-tumor effect. Thus, the compounds of the present invention are of great value as agents for alleviating side effects caused by use of an anti-tumor agent, which enable not only the chemotherapy to be continuedly carried out, but also the body exhaustion to be effectively prevented.

  • Patent number: RE47413
    Abstract: The present invention relates to pyrazine derivatives such as those represented by Formulas I and II below. X1 to X4 of the compounds of Formulas I and II may be characterized as electron withdrawing groups. In contrast, Y1 to Y4 of the compounds of Formulas I and II may be characterized as electron donating groups. Pyrazine derivatives of the present invention may be utilized in assessing renal function. In particular, an effective amount of a pyrazine derivative of the invention may be administered into a body of a patient. The pyrazine derivative that is in the body may be exposed to visible and/or infrared light to cause spectral energy to emanate from the pyrazine derivative. This emanating spectral energy may be detected and utilized to determine renal function of the patient.
