CAS No.: 7758-16-9
Synonyms: Disodium pyrophosphate; Sodium acid pyrophosphate; SAPP
Sodium pyrophosphate (Disodium pyrophosphate) is an orally active reverse transcriptase ribonuclease H inhibitor. Sodium pyrophosphate forms soluble complexes with iron from ferric pyrophosphate to promote intestinal iron absorption. Sodium pyrophosphate increases the β-sheet content of oxidatively damaged myofibrillar protein gels and enhances the gastric digestibility and antioxidant activity of their digestion products. Sodium pyrophosphate prevents the degradation of RNA-DNA hybrids, inhibits antisense complementary DNA synthesis, induces phage DNA leakage, and causes random mutations in temperate phages .

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 .
