  We have calculated the multinucleon transfer reactions of $^{208}$Os,
$^{208}$Pt, $^{208}$Hg, $^{208}$Pb,$^{208}$Po, $^{208}$Rn,
$^{208}$Ra,$^{132,136}$Xe bombarding on $^{232}$Th and $^{248}$Cm at Coulomb
barrier energies within the dinuclear system model, systematically. The results
are in good agreement with the available experimental data. Coulomb effect and
shell effect on production of actinides in these reactions have been
investigated thoroughly. Potential energy surface and total kinetic energy mass
distributions in the reactions $^{208}$Hg, $^{208}$Pb and$^{208}$Po colliding
on $^{248}$Cm and $^{232}$Th are calculated and analyzed, respectively. It is
found that PES and TKE spectra manifest the fragment formation mechanism in the
multinucleon transfer reactions. The isospin effect and shell effect are shown
in PES and TKE. Production cross-sections of multinucleon transfer products are
highly dependent on the isobar projectiles with mass number $A=208$. The isobar
projectiles with larger N/Z ratios are favorable for creating the neutron-rich
target-like fragments. The isobar projectiles with larger charge number induced
products tend to shift to proton-rich region. Coulomb potential coupled to
shell effect is shown in production cross-sections of actinide isotopes. Based
on the radioactive projectiles induced reactions, we have predicted massive new
actinide isotopes around nuclear drip lines, even could access the superheavy
nuclei region.
