Poly (ADP-ribose) Polymerase Inhibitors: Understanding

Poly (ADP-ribose) Polymerase Inhibitors: Overview

The PARP inhibitor stops the cancer cells being repaired which causes the cells to die and so reduces tumor growth. In cancers where the tumor suppressor gene is faulty the cancer cells are repaired only by PARP. The PARP repair is incomplete which means the cancer cells DNA is repaired to a point where it just has a small amount of damage and the cancer cells are able to able to grow and divide. If the PARP did not repair the DNA then the cancer cells would have too much damage in its DNA so would trigger its own death. The PARP inhibitors act to stop the cancer cells DNA being repaired by PARP, so the damaged DNA stays at the critical level that causes cell to trigger its own death and therefore inhibits the growth of the tumor.

PARP inhibitors are a class of drugs designed to target the PARP family of enzymes, which play a critical role in DNA repair. These inhibitors typically feature a structural moiety such as 1-hydroxyisoquinoline, chlorthenoxazin, 3-hydroxybenzamide, or 4-amino-1,8-naphthalimide. The PARP enzyme itself is composed of four key domains: a DNA-binding domain with zinc finger motifs, a caspase-cleaved domain, an auto-modification domain, and a catalytic domain. The catalytic domain facilitates the polymerization of ADP-ribose units from NAD+ onto target proteins. PARP inhibitors bind specifically to this catalytic domain, thereby blocking the enzyme's activity and preventing DNA repair, which ultimately leads to cell death in cancers that are heavily dependent on PARP function.

PARP inhibitors are a class of drugs that specifically target PARP enzymes, primarily PARP1, which are essential for repairing DNA single-strand breaks. By inhibiting PARP, these drugs impair the cancer cells' ability to repair DNA, leading to the accumulation of damage and eventual cell death, especially in tumors with existing deficiencies in DNA repair mechanisms, such as those harboring BRCA1 or BRCA2 mutations. This concept, known as synthetic lethality, has made PARP inhibitors highly effective in treating cancers like ovarian and breast cancers, leading to the approval of several PARP inhibitors for clinical use. Furthermore, ongoing research is investigating their potential in treating non-oncological diseases and addressing challenges such as resistance to therapy. PARP inhibitors are a promising therapeutic approach in oncology, leveraging the concept of synthetic lethality to target cancer cells with DNA repair deficiencies, such as those with BRCA mutations. By inhibiting PARPs, which are critical for DNA repair, these drugs lead to the accumulation of DNA damage in tumor cells, resulting in cell death. This strategy has proven effective in treating cancers like ovarian and breast cancer, with PARP inhibitors such as olaparib, rucaparib, and niraparib demonstrating significant clinical efficacy. Beyond oncology, PARP inhibitors show potential in conditions characterized by inflammation and reperfusion injury, where they may help mitigate cellular dysfunction and promote survival by restoring energy homeostasis and reducing necrosis.

Poly (ADP-ribose) Polymerase Inhibitors Emerging Drugs Chapters

This segment of the Poly (ADP-ribose) Polymerase Inhibitors report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Poly (ADP-ribose) Polymerase Inhibitors Emerging Drugs

AZD5305: AstraZeneca

AZD5305 is a potent and selective oral PARP inhibitor (PARPi) that specifically targets and traps PARP1, in contrast to approved PARPis which target both PARP1 and PARP2. Preclinical data suggest that PARP1 inhibition confers antiproliferative effects, while PARP2 inhibition is a major driver of hematological toxicity. Thus, AZD5305 may have an improved therapeutic index with less toxicity. The Phase III PROpel study showed that first-line olaparib plus abiraterone (abi) significantly improved radiographic progression-free survival (rPFS) over abi alone in pts with metastatic castration-resistant prostate cancer (mCRPC) enrolled irrespective of homologous recombination repair (HRR) gene mutations. Currently, the drug is in Phase III stage of its clincal trial for the treatment of Prostate cancer.

Stenoparib: Allarity Therapeutics

Stenoparib is an orally available, small-molecule dual-targeted inhibitor of PARP1/2 and Tankyrase 1 and 2. At present, tankyrases are attracting significant attention as emerging therapeutic targets for cancer, principally due to their role in regulating the Wnt signaling pathway. Aberrant Wnt/β-catenin signaling has been implicated in the development and progression of numerous cancers. By inhibiting PARP and blocking Wnt pathway activation, stenoparib’s unique therapeutic action shows potential as a promising therapeutic. Allarity has exclusive global rights for the development and commercialization of stenoparib, which was originally developed by Eisai Co. Ltd. and was formerly known under the names E7449 and 2X-121.

ACE86225106: Acerand Therapeutics

ACE-86225106 is a novel, oral, and highly selective inhibitor of poly (ADP-ribose) polymerase 1 (PARP1) developed independently by Acerand Therapeutics. It showed significant inhibitory effect on PARP1 in vitro, which was comparable with the positive controls (Olaparib, the first-generation pan-PARPi, and AZD5305, the second-generation PARP1 selective inhibitor under development), and showed no significant inhibitory effect. ACE-86225106 is expected to uphold its anti-tumor efficacy with potentially reduced hematological toxicity risks (i.e. anemia) and extended therapeutic window, thereby improving the prognosis for patients with advanced solid tumor. Currently, the drug is in Phase I/II stage of its clinical trial for the treatment of Solid Tumor.
