Abstract:
As a promising therapeutic target for cancer, CYP1B1 is overexpressed in Taxol-resistant A549 cells; however, its role in drug resistance still remains unclear. Bioinformatic analysis data indicated that CYP1B1 was closely correlated with AKT/ERK1/2 and focal adhesion pathways, thereby playing an important role in Taxol resistance and cancer migration/invasion. Along similar lines, the AhR agonist 7,12-dimethylbenz[a]anthracene (DMBA) enhanced Taxol resistance and promoted migration/invasion of A549 and H460 cells likely stemming from CYP1B1 upregulation. Moreover, 83 novel N-aryl-2,4-bithiazole-2-amine CYP1B1-selective inhibitors were designed and synthesized to verify the role of CYP1B1 in Taxol-resistant A549 cells. Impressively, the most potent and selective one, namely, 77, remarkably inhibited AKT/ERK1/2 and FAK/SRC pathways and thereby reversed Taxol resistance as well as inhibited both migration and invasion of A549/Taxol cells. Collectively, this study not only displayed the role of CYP1B1 in Taxol resistance and cancer migration/invasion but also helped unlock the CYP1B1-oriented anticancer discovery.
Insights
This study reveals that CYP1B1 promotes Taxol resistance and cancer spread by activating AKT/ERK1/2 pathways. A novel inhibitor, compound 77, successfully reversed Taxol resistance and inhibited cancer cell migration and invasion.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Cytochrome P450 family 1 subfamily B member 1 (CYP1B1) is a potential cancer therapeutic target.
- CYP1B1 is overexpressed in Taxol-resistant A549 cells, but its role in drug resistance is not fully understood.
Purpose of the Study:
- To investigate the role of CYP1B1 in Taxol resistance and cancer migration/invasion.
- To design and synthesize novel CYP1B1 inhibitors to overcome Taxol resistance.
Main Methods:
- Bioinformatic analysis to identify pathways correlated with CYP1B1.
- In vitro experiments using A549 and H460 cells treated with 7,12-dimethylbenz[a]anthracene (DMBA).
- Design, synthesis, and evaluation of novel N-aryl-2,4-bithiazole-2-amine derivatives as CYP1B1 inhibitors.
Main Results:
- Bioinformatic analysis linked CYP1B1 to AKT/ERK1/2 and focal adhesion pathways, suggesting its role in Taxol resistance and cancer metastasis.
- DMBA treatment increased Taxol resistance and promoted migration/invasion in A549 and H460 cells, associated with CYP1B1 upregulation.
- The synthesized inhibitor, compound 77, selectively inhibited CYP1B1, suppressed AKT/ERK1/2 and FAK/SRC signaling, reversed Taxol resistance, and reduced migration/invasion in A549/Taxol cells.
Conclusions:
- CYP1B1 plays a significant role in mediating Taxol resistance and facilitating cancer cell migration and invasion.
- Novel CYP1B1 inhibitors, exemplified by compound 77, hold promise for developing new anticancer strategies against Taxol-resistant cancers.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
