The role of compressible fluctuations in MHD turbulence is investigated using direct numerical simulations and in-situ spacecraft in the solar wind. A focus is put on verifying the exact third-order law derived for compressible isothermal turbulence by {\color{blue}Banerjee and Galtier (2013)}. The numerical simulations use a 3D compressible MHD code in the isothermal limit ($\gamma=1$) with low sonic Mach numbers ($M_s
