• Ab initio studies of two pyrimidine derivatives as possible photo-switch systems 

      Csehi, András; Woywod, Clemens Joachim; Halász, Gábor J.; Vibok, Agnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The six lowest lying electronic singlet states of 8-(pyrimidine-2-yl)quinolin-ol and 2-(4-nitropyrimidine-2- yl)ethenol have been studied theoretically using the complete active space self-consistent-field (CASSCF) and Møller-Plesset second-order perturbation theory (MP2) methods. Both molecules can be viewed as consisting of a frame and a crane component. As a possible mechanism for the excited-state ...
    • Dynamical models of mutated chronic myelogenous leukemia cells for a postimatinib treatment scenario: Response to dasatinib or nilotinib therapy 

      Woywod, Clemens Joachim; Gruber, Franz; Engh, Richard Alan; Flå, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-05)
      Targeted inhibition of the oncogenic BCR-ABL1 fusion protein using the ABL1 tyrosine kinase inhibitor imatinib has become standard therapy for chronic myelogenous leukemia (CML), with most patients reaching total and durable remission. However, a significant fraction of patients develop resistance, commonly due to mutated ABL1 kinase domains. This motivated development of second-generation drugs ...
    • Pyrazine excited states revisited using the extended multi-state complete active space second-order perturbation method 

      Shiozaki, Toru; Woywod, Clemens Joachim; Werner, Hans-Joachim (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      We demonstrate that the recently developed extended multi-state complete active space second-order perturbation theory (XMS-CASPT2) [Shiozaki et al., J. Chem. Phys., 2011, 135, 081106] provides qualitatively correct potential energy surfaces for low-lying excited singlet states of pyrazine, while the potential energy surfaces of the standard MS-CASPT2 methods are ill-behaved near the crossing ...
