Herein is reported a method for producing a recombinant adeno-associated viral particle (rAAVp) preparation comprising the steps of cultivating a
mammalian cell comprising a
gene encoding a non-adeno-associated-
virus gene, which is operably linked to two AAV inverted
terminal repeats (ITRs) (i.e. the non-adeno-associated
virus gene is interspaced between the two AAV ITRs), a gene encoding the AAV Cap
protein VP1 and / or VP3, a gene encoding the AAV Rep
protein Rep78 or Rep68 and / or a gene encoding the AAV Rep
protein Rep52 or Rep40, a gene encoding the adenoviral helper function E4orf6, and a gene encoding the adenoviral helper function E2A, recovering the rAAVp from the
cell and / or the cultivation medium, and thereby producing the rAAVp preparation, whereby the cultivating of the
mammalian cell is in the presence of at least one compound selected from one of the following groups of compounds the
caspase inhibitor Q-VD-OPh and IDN6556,
DNA damage response activation inducing substances, including ATM / ATR inducing substances, antiviral response inhibitors,
AMPK activators,
oxidative phosphorylation agents, inhibitors of κB
kinase, dNTP synthesis enhancers, including co-factors and building blocks, and
cell cycle modulators.
