Adavosertib is a potent and selective oral inhibitor of the WEE1 kinase, a key regulator of the G2/M and S phase cell-cycle checkpoints. by Caroline Hopkins CHICAGO AstraZenecas investigational WEE1 inhibitor adavosertib showed potential in biomarker-selected advanced ovarian cancer populations in two studies presented during the American Society of Clinical Oncologys annual meeting Saturday. The drug, which AstraZeneca licensed from Merck in 2013, is designed to target the WEE1 Contact Us; LiveHelp Online Chat Adavosertib is a potent and selective Wee1 inhibitor (IC 50 = 5.2 nM). -Mutated Ovarian Cancer. Small molecule WEE1 kinase inhibitor.
CHICAGO AstraZeneca's investigational WEE1 inhibitor adavosertib showed potential in biomarker-selected advanced ovarian cancer populations in two studies presented during the American Society of Clinical Oncology's annual meeting Saturday. Mechanism of Action. The Wee1 (WEE1hu) inhibitor adavosertib and gemcitabine have shown preclinical synergy and promising activity in early phase clinical trials. We aimed to determine the efficacy of this combination in patients with ovarian cancer. Adavosertib selectively targets and inhibits WEE1, a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDK1, CDC2) to inactivate the CDC2/cyclin B complex. Description: MK-1775, also known as Adavosertib and AZD-1775, is a small molecule inhibitor of the tyrosine kinase WEE1 with potential antineoplastic sensitizing activity. The Wee1 inhibitor adavosertib is used in a number of previous and ongoing clinical trials. Azoles of two nitrogens at the 1,2 positions, next to each other, in contrast with IMIDAZOLES in which they are at the 1,3 positions. Adavosertib (MK-1775, AZD1775) is a potent and selective Wee1 inhibitor with IC50 of 5.2 nM in a cell-free assay; hinders G2 DNA damage checkpoint. Phase 2. Adavosertib (MK-1775, AZD1775) is a potent and selective Wee1 inhibitor with IC50 of 5.2 nM in a cell-free assay; hinders G2 DNA damage checkpoint. We were also very interested in looking for things that predicted who might respond from the Wee1 inhibitor alone versus who might benefit from the combination. WEE1 is a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDK1) to inactivate the CDC2/cyclin B complex. Reference: Cole KA, et al.
A small molecule inhibitor of WEE1, AZD1775 (Adavosertib) (31, 32), significantly decreased cell growth, increased G2/M cell cycle arrest and apoptosis in resistant cells compared with respective parental sensitive cells. Adavosertib selectively targets and inhibits WEE1, a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDK1, CDC2) to inactivate the CDC2/cyclin B complex. Adavosertib is a specific, ATP competitive and highly selective inhibitor of the Wee1 kinase. Facebook; Twitter; Instagram; YouTube; LinkedIn; CONTACT INFORMATION. Adavosertib (development codes AZD1775, MK-1775) is an experimental anti-cancer drug candidate. Inhibiting the activity of WEE1 prevents the phosphorylation of CDC2 and impairs the G2/M checkpoint. The goal of the current study was to test drugs in combination with adavosertib that might magnify its effect. Looking ahead, because of the satisfaction with the preliminary findings in this expansion trial, Cole noted that an adavosertib pediatric development plan is being discussed. Wee1 inhibition in p53-deficient tumors by Adavosertib has been shown to inhibit and regress tumor growth (2). WEE1 suppresses CDK1 and CDK2 kinase activities to regulate the G1/S transition after the origin licensing is complete. It is being developed by AstraZeneca. Since most human cancers harbor p53-dependent G1 checkpoint abnormalities, they are dependent on the G2 checkpoint. In preclinical studies, adavosertib enhances the antitumor effect of chemotherapy and radiation, particularly among those tumors that have a TP53 mutation [5964].
It covers the pipeline drug profiles, including clinical and nonclinical stage products. Classification. For research use only. From the NCI Drug Dictionary: A small molecule inhibitor of the tyrosine kinase WEE1 with potential antineoplastic sensitizing activity. IC 50 & Target. Preclinical evidence suggests that the combination of MK-1775 and DNA damage-inducing chemotherapy agents can enhance anti-tumor properties, in comparison to chemotherapy alone. We show that WEE1i induces CDK1-dependent RIF1 phosphorylation and CDK2- and CDC7-dependent activation of the replicative helicase. Further studies of adavosertib in this patient population are planned. 3.1 WEE1 inhibitor and ATR inhibitor show synergy in multiple cancer lineages. AZD1775 (adavosertib) is an inhibitor of the Wee1 kinase. In a panel of 223 serine/threonine or tyrosine kinases, Adavosertib is highly selective for Wee 1 over all except 8 kinases. TP53 mutation is one of the most frequent gene mutations in head and neck squamous cell carcinoma (HNSCC) and could be a potential therapeutic target. SCLC tumours have relatively low immunogenicity. Neuroendocrine neoplasms (NENs) represent a rare and heterogeneous group of malignancies, sharing features of both neural and endocrine cells. 24 Publications Citing Use of MCE Adavosertib WEE1. IC50: 5.2 nM (Wee1) . Pediatric phase 2 trial of the WEE1 inhibitor adavosertib (AZD1775) and irinotecan; A Childrens Oncology Group Study (ADVL1312). Patients were given 300 mg of adavosertib per day on days 1 through 5 and 8 through 12 of a 21-day cycle. The Wee1 (WEE1hu) inhibitor adavosertib and gemcitabine have shown preclinical synergy and promising activity in early phase clinical trials. TP53. It abrogates a DNA damage checkpoint (G2-phase), leading to apoptosis in combination with several DNA-damaging agents selectively in p53-deficient tumor cell lines. MK-1775 selectively targets and inhibits WEE1, a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDC2), to inactivate the CDC2/cyclin B complex. Nat Rev Clin Oncol.

However, the drugs effectiveness has overall been promising but not perfect. Tayob N, Kochupu-rakkal B, et al. Adavosertib (AZD-1775; MK-1775) is a potent Wee1 inhibitor with an IC50 of 5.2 nM. Leah Lawrence. Adavosertib (AZD1775) is a potent, selective, small-molecule WEE1 inhibitor. Synonyms: MK-1775, AZD1775, Adavosertib MK-1775 MK-1775 is a small molecule inhibitor of the checkpoint kinase WEE1 (IC50: 5.2 nM). PMID: 32611648 Additional adavosertib doses within the chemotherapy treatment cycle or the potential for maintenance therapy for adavosertib should be considered to increase clinical benefit in future studies. Palve et al. Adavosertib is a potent and selective oral inhibitor of the WEE1 kinase, a key regulator of the G2/M and S phase cell-cycle checkpoints. Features: The first reported Wee1 inhibitor. Looking ahead, because of the satisfaction with the preliminary findings in this expansion trial, Cole noted that an adavosertib pediatric development plan is being discussed. In a panel of 223 serine/threonine or tyrosine kinases, Adavosertib is highly selective for Wee 1 over all except 8 kinases. References: Stewart A, et al. Adavosertib (AZD-1775; MK-1775) is a potent Wee1 inhibitor with an IC50 of 5.2 nM. The WEE1 kinase inhibitor AZD1775 (WEE1i) induces origin firing in replicating cells. WEE1 kinase inhibition. The WEE1 inhibitor adavosertib improved progression-free survival with a tolerable safety profile compared with active monitoring in patients with RAS/TP53-mutated metastatic colorectal cancer. They performed a drug screen with 240 targeted compounds and discovered that the strongest hit was with the WEE1/PLK1 inhibitor adavosertib. Adavosertib (MK-1775) enhances the cytotoxic effects of 5-FU in p53-deficient human colon cancer cells. In particular Adavosertib We do not sell to patients. Adavosertib is a potent and selective Wee1 inhibitor (IC 50 = 5.2 nM). We found that adavosertib treatment led to obvious multinucleation and micronucleation, which are representative markers of mitotic catastrophe, suggesting serious mitotic catastrophe induced after WEE1 inhibition ( Fig. 3 C, D). About Adavosertib (AZD1775) Adavosertib is a small molecule Wee1 inhibitor of the tyrosine kinase WEE1 with potential cancer sensitizing activity that can make some cancer cells more vulnerable to anti-cancer therapy and enhance its cytotoxic effect. 17 Preclinical studies show that AZD1775 plus chemotherapy can enhance treatment efficacy in ovarian cancer. The aggressive endometrial cancer, uterine serous carcinoma (USC) is hypothesized to have a unique sensitivity to WEE-1 inhibition, based on the fact that TP53 mutations are seen in 90% of cases. Small molecule WEE1 kinase inhibitor.
