Synonyms: PR-1498487

Target:  

ADC Antibodies

Research Areas:  

Cancer

Samrotamab (PR-1498487) is a humanized IgG1-κ chimeric monoclonal antibody targeting LRRC15, with a Kd of 5.42 nM for human LRRC15. Samrotamab can be used to synthesize antibody-drug conjugates (ADC). Samrotamab disrupts the LRRC15-SCG5 signaling module, binds to a membrane-proximal conformational epitope within the C-terminal leucine-rich repeat region of LRRC15, and binds to the lateral edge of the LRR solenoid while leaving the canonical concave β-sheet surface fully exposed. Samrotamab reduces the viability of bladder cancer cells, inhibits clonogenic growth, impairs cell migration, and compromises cell invasion. Samrotamab induces compensatory upregulation of LRRC15 transcripts while suppressing the expression of SCG5 mRNA. Samrotamab is applicable to research related to urothelial carcinoma, sarcoma, osteosarcoma, and undifferentiated pleomorphic sarcoma .

Target:  

Amyloid-β

Research Areas:  

Neurological Disease

β-Sheet Breaker Peptide iAβ5 is an effective brain amyloid-β (Abeta) degrader. Abeta deposits are associated with Alzheimer's disease (AD), and the related toxicity arises from its β-sheet conformation and aggregation. β-Sheet Breaker Peptide iAβ5 can repeatedly induce the degradation of fibrillary amyloid deposits in vivo. Therefore, β-Sheet Breaker Peptide iAβ5 can prevent and/or reverse neuronal contraction caused by Abeta and reduce the range of interleukin IL-1beta positive microglial-like cells around Abeta deposits. β-Sheet Breaker Peptide iAβ5 can reduce the size and/or number of brain amyloid plaques in AD. β-Sheet Breaker Peptide iAβ5 is labeled with a hydrophobic benzyl alcohol (HBA) tag and shows a bright blue color under acidic conditions, which can be used for quantitative determination.

Withanoside V is a blood-brain barrier-permeable withanolide derivative . Withanoside V binds strongly to Sudlow I (domain IIA) of human serum albumin (HSA) to form a stable complex and alter the secondary structure of albumin, thereby increasing helix content and reducing β-sheet and random coil. Withanoside V binds to Aβ (1-42) to block the interaction between monomers and subsequent aggregation. Withanoside V inhibits the viability of neuroblastoma cells, reduces the number of apoptotic cells induced by Aβ (1-42), and decreases ROS production. Withanoside V inhibits SARS-CoV-2 Mpro. Withanoside V can be used for research on Alzheimer's disease and coronavirus disease 2019 .
