== Publication Abstract from PubMed ==
Structure based drug design of a series of novel 1,4-benzoxazin-3-one derived PARP-1 inhibitors are described. The synthesis, enzymatic &amp; cellular activities and pharmacodynamic effects are described. Optimized analogs demonstrated inhibition of poly-ADP-ribosylation in SW620 tumor bearing nude mice through 24h following a single dose.


==Function==
Discovery of novel benzo[b][1,4]oxazin-3(4H)-ones as poly(ADP-ribose)polymerase inhibitors.,Gangloff AR, Brown J, de Jong R, Dougan DR, Grimshaw CE, Hixon M, Jennings A, Kamran R, Kiryanov A, O'Connell S, Taylor E, Vu P Bioorg Med Chem Lett. 2013 Aug 15;23(16):4501-5. doi: 10.1016/j.bmcl.2013.06.055., Epub 2013 Jun 24. PMID:23850199<ref>PMID:23850199</ref>
[[http://www.uniprot.org/uniprot/PARP1_HUMAN PARP1_HUMAN]] Involved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. With EEF1A1 and TXK, forms a complex that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production.<ref>PMID:17177976</ref> <ref>PMID:18172500</ref> <ref>PMID:19344625</ref> <ref>PMID:19661379</ref>
