2-Methoxyestrone- 13C6 is the 13C-labeled 2-Methoxyestrone (HY-113252). 2-Methoxyestrone is an estrogen metabolite with antimitotic activity. 2-Methoxyestrone acts as a liver-specific prohormone that undergoes demethylation to form active 2-hydroxyestrogens, and it can also interconvert with 2-Methoxyestradiol (HY-12033) via the 17β-hydroxysteroid dehydrogenase pathway. In the presence of all-trans retinoic acid, 2-Methoxyestrone exerts a strong, concentration-dependent inhibitory effect on cell growth. 2-Methoxyestrone delays the progression of pulmonary hypertension in rats, alleviates right ventricular and pulmonary vascular remodeling, and relieves proliferative pulmonary hypertension in rats. 2-Methoxyestrone can be used in studies related to proliferative pulmonary hypertension .

FAM labled Ultevursen sodiumis a FAM labled Ultevursen sodium (HY-147412A). Ultevursen sodium (QR-421a) is a splice-modulating antisense oligonucleotide targeting exon 13 of the USH2A gene, which restores the functional expression of Usherin protein by inducing exon skipping. Ultevursen sodium binds to USH2A pre-mRNA and modulates the splicing process to specifically skip exon 13 carrying the pathogenic mutation c.2299delG, generating an in-frame transcript and a truncated yet functionally normal protein. Ultevursen sodium exhibits concentration-dependent exon skipping activity in human cells and retinal organoid models, and restores Usherin expression and retinal function in zebrafish and gene-edited mouse models. Ultevursen sodium can be used for related research on type 2 Usher syndrome and non-syndromic retinitis pigmentosa .

Parethoxycaine (Intracaine) is an ester-type local anesthetic that possesses dual activities as a non-selective inhibitor and agonist potentiator in smooth muscle, while acting as a mixed-type inhibitor of cytochrome c oxidase at the enzyme level. Parethoxycaine non-competitively inhibits the contraction of guinea pig ileal longitudinal muscle by interfering with transmembrane Ca 2+ transport (blocking K +/CD responses in an equi-effective manner), and potentiates norepinephrine (NA) responses in rat vas deferens by blocking NA uptake and promoting Ca 2+ mobilization (increasing the maximum amplitude without affecting K + responses). Parethoxycaine inhibits the activity of purified cytochrome c oxidase in a concentration-dependent manner, and can be used in research focusing on Ca 2+ signal transduction, smooth muscle contraction regulation, and mitochondrial energy metabolism .

Cremophor EL-10 is a nonionic polyoxyethylene castor oil surfactant with multiple functions including organic solubilizer, mixed zinc anode corrosion inhibitor and dendrite growth inhibitor. By forming a physical barrier to block electrolyte contact and constructing oriented hydration channels to reduce the desolvation energy barrier of Zn 2+ , Cremophor EL-10 achieves a corrosion inhibition efficiency of over 99%. Cremophor EL-10 exerts no significant effects on the mitochondrial activity and cell viability of epithelial cells, making it suitable for in vitro drug delivery and biopharmaceutical research at concentrations ≤10% v/v. However, Cremophor EL-10 may induce sustained non-endothelium-dependent contraction in rat aortic rings and exert concentration-dependent inhibitory effects on acetylcholine-induced endothelium-dependent relaxation responses .

Tz-Thalidomide (Standard) is the analytical standard of Tz-Thalidomide (HY-101460). This product is intended for research and analytical applications. Tz-Thalidomide is a tetrazine-tagged Thalidomide (HY-14658), an E3 ligase ligand. Tz-Thalidomide self-assembles with TCO-labeled target protein inhibitors, forming a CLIP-TAC (targeted protein degradation chimera) via click chemistry. This chimera recruits the E3 ubiquitin ligase CRBN to the target protein, thereby inducing ubiquitination and subsequent degradation of the target protein. When used in combination with JQ1-TCO (HY-148864), Tz-Thalidomide induces concentration-dependent degradation of BRD4 in cells. When combined with ERK-targeting protein inhibitors, Tz-Thalidomide induces degradation of ERK1/2 in cells. Tz-Thalidomide can be used in cancer-related research .

Seglitide (MK-678) is an orally active, selective SSTR2 agonist and somatostatin analog. Seglitide also acts as a competitive Somatostatin receptor antagonist, with pA2 values of 6.50, 6.24 and 6.09 against SS14, SS25 and SS28, respectively. Seglitide produces only weak, transient inhibition of myocardial contractility in isolated right atria of guinea pigs. Seglitide inhibits glucagon secretion and reduces circulating insulin levels. Seglitide causes a sustained, reversible reduction in elevated systolic blood pressure in streptozotocin (HY-13753)-induced diabetic rats, but exerts no effect on spontaneously hypertensive rats. Seglitide induces membrane hyperpolarization and inhibits electrical excitability. Seglitide induces concentration-dependent contraction and significant desensitization in isolated distal colon of rats.
