T1123

Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.

Estradiol 3-sulfamate (BLE 00084) is an orally active and highly potent steroidal estrone sulfatase (ES) inhibitor.Estradiol 3-sulfamate has a K(i) value of 73 nM for ES in human placental microsomes and can be used in the study of breast cancer.

Giredestrant tartrate (Estrogen receptor antagonist 1) is a novel, orally active, selective and effective non-steroidal estrogen receptor antagonist. Giredestrant tartrate strongly binds to ER, resulting in the failure of ER to activate the transcription of targeted genes and promoting the degradation of ER protein. Giredestrant tartrate can be used to treat tumor diseases.

Camizestrant (Estrogen receptor antagonist 2) is an antagonist of the estrogen receptor and can be used in studies about ER+ HER2-advanced breast cancer[1].

Camizestrant TFA (AZD-9833 TFA) is a potent and orally active antagonist of estrogen receptor (ER).

ERRγ Inverse Agonist 1 (Compound 12) is a potent, selective, and orally bioavailable estrogen-related receptor gamma (ERRγ) inverse agonist with an IC50 of 40 nM [1].

Erythromycin thiocyanate is a macrolide antibiotic produced by actinomycetes with a broad antibacterial spectrum. It inhibits RNA-dependent protein synthesis by binding to the bacterial 50S ribosomal subunit and blocking transpeptidation and translocation, without interfering with nucleic acid synthesis. It has also shown antitumor and neuroprotective activities in multiple studies.

ESI-08 is an effective antagonist of EPAC2 with an IC50 of 8.4 μM. ESI-08 selectively blocks cAMP-induced EPAC activation but not cAMP-mediated PKA activation.

Etamicastat can be used in the research of cardiovascular diseases. Etamicastat (BIA 5-453) is a potent and reversible dopamine-β-hydroxylase (DBH) inhibitor with an IC50 value of 107 nM.

Etamicastat hydrochloride (BIA 5-453 hydrochloride) is a peripherally selective dopamine beta-hydroxylase inhibitor that reduces hypertension.

Ethacizine hydrochloride (NIK-244) has antiarrhythmic activity, and its effects are related to cardiac activity and can be used to study arrhythmias and myocardial infarction.

Camptothecin-D5 is a deuterated derivative of Camptothecin (T1123) (CPT), an alkaloid and an inhibitor of DNA topoisomerase I (Topo I) with an IC50 value of 679 nM. Camptothecin (T1123) (CPT) exhibits potent antitumor activity against colorectal, breast, lung, and ovarian cancers by modulating the expression pattern of miRNA and regulating the activity of hypoxia-inducible factor-1α (HIF-1α) in human cancer cells.
