ABSTRACT
Radioactive isotope, also called radioisotope,  any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. Radioisotopes are elements that are atomically unstable and radioactive. Radioisotopes stabilize by releasing energy and matter. Natural radioisotopes, which have relatively low radioactive energy, have been largely replaced by artificially produced radioisotopes. Artificially produced radioisotopes are widely utilized as sources of radiation for radiography, gauging, and as tracers for a multitude of measurements that are not easily made by other methods. Radiopharmaceuticals are drugs containing a radionuclide and are used routinely in nuclear medicine for the diagnosis and therapy of various diseases. Presented article is concerned with brief discussion about the radioisotope & Radiopharmaceuticals.

ABSTRACT
Pyrazole, a 5-membered heterocyclic diazole alkaloid composed of three carbon atoms and two nitrogen atoms in adjacent positions, is a prevalent scaffold in drug discovery programs. The aim of this review is to provide an overview of diverse pharmacological activities of pyrazole moiety.This review highlighted recent reports of antimicrobial, anticancer, ACE inhibitory, antiviral as well as anti-inflammatory activities of pyrazole. The purpose of this review was to collate literature work reported by researchers on pyrazole for their varoius pharmacological activities and also reported recent efforts made on this moiety.

ABSTRACT
Heterocyclic chemistry is the branch of chemistry dealing with structure,synthesis, properties, and applications of heterocycles. heterocyclic compounds may be inorganic, most contain at least one carbon. Since in organic chemistry non-carbons usually are considered to replace carbon atoms, they are called heteroatoms, meaning 'different from carbon and hydrogen' (rings of heteroatoms of the same element are homocyclic). The IUPAC recommends the Hantzsch-Widman nomenclature for naming heterocyclic compounds.The present review article is based on the condenced heterocyclic system quinoline derivatives with their tremendous pharmacological activities.
