CYP1A1-Mediated Intramolecular Rearrangement of Aminoazepane in GDC-0339
Drug Metab Dispos 2017 Oct;45(10):1084-1092.PMID:28790146DOI:10.1124/dmd.117.076786.
GDC-0339 is a novel small molecule pan-Pim kinase inhibitor that was discovered as a potential treatment of multiple myeloma. During the in vitro and in vivo metabolite profiling of GDC-0339, a metabolite was detected that had the same elemental composition as the parent but was distinct with respect to its chromatographic separation and mass spectrometric fragmentation pattern. High resolution tandem mass spectrometry data indicated the metabolite was modified at the aminoazepane moiety. The structure was solved by nuclear magnetic resonance analysis of the isolated metabolite and further confirmed by comparing it to a synthetic standard. These results indicated that the metabolite was formed by an intramolecular amine replacement reaction with the primary amine forming a new attachment to pyrazole without any change in stereochemistry. In vitro experiments showed cytochrome P450s catalyzed the reaction and demonstrated high isoform selectivity by CYP1A1. Results from kinetic experiments showed that the CYP1A1-mediated rearrangement of GDC-0339 was an efficient reaction with apparent turnover number (kcat) and Michaelis constant (Km) of 8.4 minutes-1 and 0.6 μM, respectively. The binding of GDC-0339 to the cytochrome P450 active site was examined by characterizing the direct inhibition of CYP1A1-mediated phenacetin O-deethylation, and GDC-0339 was a potent competitive inhibitor with Ki of 0.9 μM. This high affinity binding was unexpected given a narrow active site for CYP1A1 and GDC-0339 does not conform structurally to known CYP1A1 substrates, which are mostly polyaromatic planar molecules. Further, we explored some of the structural requirements for the rearrangement reaction and identified several analogs to GDC-0339 that undergo this biotransformation.
Optimization of Pan-Pim Kinase Activity and Oral Bioavailability Leading to Diaminopyrazole (GDC-0339) for the Treatment of Multiple Myeloma
J Med Chem 2019 Feb 28;62(4):2140-2153.PMID:30715878DOI:10.1021/acs.jmedchem.8b01857.
Pim kinases have been targets of interest for a number of therapeutic areas. Evidence of durable single-agent efficacy in human clinical trials validated Pim kinase inhibition as a promising therapeutic approach for multiple myeloma patients. Here, we report the compound optimization leading to GDC-0339 (16), a potent, orally bioavailable, and well tolerated pan-Pim kinase inhibitor that proved efficacious in RPMI8226 and MM.1S human multiple myeloma xenograft mouse models and has been evaluated as an early development candidate.
Human Cytochrome P450 1A1 Adapts Active Site for Atypical Nonplanar Substrate
Drug Metab Dispos 2020 Feb;48(2):86-92.PMID:31757797DOI:10.1124/dmd.119.089607.
The human cytochrome P450 1A1 (CYP1A1) is well known for chemical activation of procarcinogens and often has a substrate scope of small and highly planar compounds. Substrates deviating from these characteristics are certainly known, but how these larger and nonplanar substrates are accommodated and oriented within the CYP1A1 active site is not understood. Herein a new X-ray structure of CYP1A1 bound to the pan-Pim kinase inhibitor GDC-0339 reveals how the CYP1A1 active site cavity is reconfigured to bind larger and nonplanar compounds. The shape and size of the cavity are controlled by structural elements in the active site roof, with major changes in the conformation of the F helix break and relocation of Phe224 from the active site to the protein surface. This altered CYP1A1 active site architecture is consistent with the proposed mechanism for CYP1A1 generation of an unusual aminoazepane-rearranged metabolite for this substrate. SIGNIFICANCE STATEMENT: Cytochrome P450 1A1 metabolizes drugs, procarcinogens, and toxins and although previous structures have revealed how its stereotypical planar, aromatic compounds are accommodated in the CYP1A1 active site, this is not the case for flexible and nonplanar compounds. The current work determines the X-ray structure of CYP1A1 with such a flexible, nonplanar Pim kinase inhibitor, revealing significant modification of the CYP1A1 roof that accommodate this preclinical candidate and support an unusual intramolecular rearrangement reaction.
