ds-2

DS-2969 is a compound that has antibacterial activity.

This peptide is a scrambled sequence of NADPH oxidase assembly peptide inhibitor gp91 ds-tat. It is used as a control peptide. It is two amino acid residues shorter at the N-terminus compared to the scrambled gp91 ds-tat.

DS-2248 is a potent Hsp90 inhbitor, currently in phase I trials.

DS-22-inf-021, a neuraminidase (NA) inhibitor, exhibits antiviral activity against influenza viruses [1].

Positive allosteric modulator of δ-subunit containing GABAA receptors

Datopotamab deruxtecan (DS-1062) is a trophoblast cell surface antigen 2 (TROP2)-targeted antibody-drug conjugate (ADC) with antitumor activity. Datopotamab deruxtecan induces significant antibody-dependent cellular cytotoxicity in the presence of peripheral blood lymphocytes and inhibits tumor growth in xenograft models.

Valemetostat tosylate is a dual inhibitor of EZH1 2 and used in the research of relapsed refractory peripheral T-cell lymphoma.

Valemetostat (DS-3201) is an EZH1 2 inhibitor that can be used to study relapsed refractory peripheral T-cell lymphoma.

Milademetan is a potent and selective MDM2 inhibitor. MDM2 inhibitor DS-3032b binds to and prevents the binding of MDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53 upon oral administration. By preventing this MDM2-p53 interaction, the proteosome-mediated enzymatic degradation of p53 is inhibited and the transcriptional activity of p53 is restored. This results in the restoration of p53 signaling and leads to the p53-mediated induction of tumor cell apoptosis.

DS-7423 is a dual PI3K and mTOR inhibitor, with IC50 values of 15.6 nM and 34.9 nM for PI3Kα and mTOR, respectively, and exhibits anti-tumor activity[1][2]. It increases TP53 expression, the level of p-TP53 on Ser-46, and induces apoptosis-related TP53 target genes (TP53AIP1 and PUMA) in OCCC cells[1]. DS-7423 also inhibits other isoforms of class I PI3K with IC50 values of 1,143 nM for PI3Kβ, 249 nM for PI3Kγ, and 262 nM for PI3Kδ[2]. [1]. Katsutoshi Oda, et al.
