Abstract	The simultaneous optical-to-gamma-rays observations of blazars are key tools in understanding the nature of these sources, the mechanisms of the gamma-ray emission and other features, such as the origin of the soft X-rays (E < 1 keV) photon deficit, often observed in high-z flat-spectrum radio quasars. We therefore ask for two 500 ks observations with INTEGRAL (total requested exposure 2x 500 = 1000 ks) of the two high-redshift blazars PKS B2126-158 (z = 3.268) and PKS B2149-307 (z = 2.345). These observations, coupled with simultaneous Swift and GLAST observations, will allow us to build the best available optical-to-gamma-rays spectral energy distributions, which in turn will be modeled and studied in order to give answers to the above mentioned problems.

Mission Description	The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
