Initial conditions of high-mass star formation are poorly understood. This process starts with infall stage that could be detected by blue asymmetry on optically thick line profiles. Our goal is to search for signatures of such motions for the sample of high-mass star-forming cores that are probably at different stages of evolution. The sample includes 8 regions associated with young stellar objects and 7 IRDCs previously observed with SEST, APEX and Parkes telescopes. We propose Mopra observations in the HCN(1-0) and HCO+(1-0) line profiles that could be effective indications of systematic motions. The observations in the H13CN(1-0) and H13CO+(1-0) optically thin lines are also crucial for this purpose. The SiO(2-1) line will be used to search for outflows. In addition, the CH3CCH(5-4), HNC(1-0) and HN13C(1-0) lines will be observed to determine and to compare physical and chemical properties of the cores.
