protein-lysine-oxidase (LOX) inhibitor, antifibrotic,  PXS 5505, LOX inhibitor PXS-5505, LOX-IN-3, pan-LOX inhibitor PXS-5505, DO94E28WYW, SNT 5505


Amsulostat is an orally available, small-molecule, irreversible inhibitor of all lysyl oxidases (LOX) family members, with potential antifibrotic activity. Upon oral administration, amsulostat targets, binds to and inhibits the activity of all enzymes in the LOX family. This prevents the post-translational oxidative deamination of lysine residues on target proteins, including collagen and elastin, and reduces the formation of deaminated lysine (allysine), the formation of inter- and intramolecular cross-linkages and may prevent remodeling of the extracellular matrix (ECM), thereby reducing fibrotic tissue formation in certain chronic fibrotic diseases. LOX is often upregulated in fibrotic tissue and plays a key role in fibrosis.

Amsulostat (formerly PXS-5505) is an orally available, investigational, pan-lysyl oxidase (pan-LOX) inhibitor designed by Syntara to treat fibrotic diseases and solid tumors. It works by preventing collagen cross-linking and remodeling of the extracellular matrix, effectively reducing fibrosis. The drug is currently in Phase 2 clinical trials for myelofibrosis, showing promise in reducing symptom burden and spleen volume, and is also being studied for myelodysplastic syndrome (MDS) and pancreatic cancer. 

Key Aspects of Amsulostat:

  • Mechanism of Action: Irreversibly inhibits all LOX family members (LOX, LOXL1-4), reducing fibrotic tissue.
  • Clinical Status (Myelofibrosis): Phase 2a data showed 73% of patients (who were suboptimal responders to ruxolitinib) achieved  reduction in total symptom score, with significant spleen volume reduction.
  • Clinical Status (Other Cancers): Phase 2 trials (AZALOX) are evaluating its use in myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML). It is also being tested in combination with chemotherapy for pancreatic cancer to improve drug delivery to tumors.
  • Regulatory Status: Has received Orphan Drug Designation for primary myelofibrosis from the FDA (USA) and EMA (Europe).
  • Safety Profile: Clinical trials have reported it is well-tolerated with no treatment-related serious adverse events in early findings.

Amsulostat's ability to target the stiff, fibrotic environment surrounding tumors makes it a promising "add-on" therapy to increase the effectiveness of existing cancer treatments, including chemotherapy and immunotherapy.

Andamertinib

 

Andamertinib

CAS 2254145-43-0

MF C31H36N8O3 MW568.7 g/mol

N-[4-methoxy-2-[4-(3-methoxyazetidin-1-yl)piperidin-1-yl]-5-[[6-(1-methylindazol-5-yl)pyrimidin-4-yl]amino]phenyl]prop-2-enamide

N-(4-methoxy-2-[4-(3-methoxyazetidin-1-yl)piperidin-1-yl]-5-{[6-(1-methyl-1H-indazol-5-yl)pyrimidin-4-yl]amino}phenyl)prop-2-enamide
epidermal growth factor receptor tyrosine kinase inhibitor, antineoplastic, PLB 1004, 5X3KAG7ZBW

Andamertinib (also known as PLB1004) is an investigational, orally bioavailable, and irreversible small-molecule inhibitor of the epidermal growth factor receptor (EGFR). It is primarily being developed to treat non-small cell lung cancer (NSCLC) with specific genetic mutations. 

Key Clinical & Therapeutic Features

  • Target Mutations: It specifically targets EGFR exon 20 insertion (ex20ins) mutations, which are often resistant to standard first- and second-generation EGFR inhibitors.
  • Broad Selectivity: Beyond ex20ins, it also shows activity against classical mutations like Del19, L858R, and the resistance mutation T790M.
  • Brain Penetration: Andamertinib is designed to cross the blood-brain barrier, making it potentially effective for patients with brain metastases.
  • Clinical Performance: In phase 2 studies (e.g., the KANNON study), it demonstrated a confirmed objective response rate (ORR) of 42.7% and a median progression-free survival of 6.2 months in pretreated patients. 

Regulatory Status (as of Early 2026)

  • China: A New Drug Application (NDA) was accepted by the National Medical Products Administration (NMPA) in May 2025 and granted priority review for treating NSCLC with EGFR ex20ins mutations.
  • Global: It remains in various stages of clinical trials globally, including studies for first-line treatment and combination therapies with other agents like vebreltinib

Andamertinib is an orally bioavailable, mono-anilino-pyrimidine, mutant-selective epidermal growth factor receptor (EGFR) inhibitor, with potential antineoplastic activity. Upon oral administration, andamertinib targets, binds to and irreversibly inhibits the activity of various EGFR mutations, including exon 20 insertion (Ex20ins) activating mutations, the gatekeeper mutation T790M, ExDel19, and L858R. This prevents EGFR-mediated signaling, induces cell death and inhibits tumor growth in tumor cells expressing these EGFR mutations. EGFR, a receptor tyrosine kinase mutated in many tumor cell types, plays a key role in tumor cell proliferation and tumor vascularization.
