Product Description
WYC-210, an analogue of Tazarotene, is a retinoid with low anti-cancer activity. WYC-210 is a reagent for click chemistry. It contains Alkyne groups and could undergo CuAAc (copper-catalyzed azide-alkyne cycloaddition reaction) with compounds bearing an Azide group.
WYC-210 (CAS 2131803-93-3) is a retinoid compound and a derivative of the anti-psoriatic drug Tazarotene. It has the molecular formula C₁₈H₁₆N₂O₃S and a molecular weight of 340.40 g/mol. Unlike its parent compound, WYC-210 exhibits lower anticancer activity. It is classified as a click chemistry reagent containing an alkyne group, which enables it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with azide-containing molecules. WYC-210 is intended for research use only, primarily as a tool in chemical biology and drug discovery.
Product Application
Overview
WYC-210 is a synthetic retinoid analogue structurally related to tazarotene, developed for specialized research applications in chemical biology and molecular modification. Supplied by InvivoChem, this compound is distinguished by its incorporated alkyne functional groups, which enable participation in click chemistry reactions.
While WYC-210 exhibits relatively low anti-cancer activity compared to other retinoids, its value lies in its versatility as a chemical probe. The presence of reactive alkyne moieties allows researchers to selectively attach WYC-210 to azide-containing molecules, making it a useful tool for studying molecular interactions, labeling, and conjugation strategies.
Its retinoid backbone also makes it relevant in studies exploring retinoid signaling pathways, differentiation processes, and structure-activity relationships within this class of compounds.

Mechanism of Action
WYC-210 functions primarily as a reactive intermediate in click chemistry workflows. The alkyne groups within its structure readily participate in copper-catalyzed azide-alkyne cycloaddition (CuAAC), forming stable triazole linkages when combined with azide-bearing compounds.
This reaction is highly specific, efficient, and bioorthogonal, allowing it to occur in complex biological environments without interfering with native biochemical processes. As a result, WYC-210 can be used to tag, track, or modify biomolecules with precision.
Although structurally related to retinoids, its biological activity is secondary to its utility as a chemical tool in conjugation and labeling experiments.

Research Applications
WYC-210 is widely applied in click chemistry, chemical biology, and drug discovery research. It is particularly useful for bioconjugation, molecular tagging, and the development of functionalized compounds for imaging or mechanistic studies.
Researchers may also explore its use in studying retinoid analogues, receptor interactions, and differentiation pathways, benefiting from its modified structure and reduced biological interference.
InvivoChem supplies WYC-210 with full supporting documentation, including COA, SDS, and instructions for use, ensuring reliable integration into laboratory workflows.
For projects requiring precise conjugation chemistry or functional retinoid analogues, WYC-210 offers a flexible, research-focused option. Reach out to InvivoChem to discuss your application needs.

Biological Activity I Assay Protocols (From Reference)
Targets
Retinoid receptors (e.g., RAR or RXR) are the primary targets for Tazarotene and other retinoids. As a Tazarotene derivative, WYC-210 likely interacts with these nuclear receptors, although its specific binding affinity and selectivity have not been fully characterized. Its reported lower anticancer activity compared to Tazarotene suggests a potentially different or reduced interaction with these targets.
ln Vitro
B16-F1 TRC cell proliferation is inhibited by WYC-210 (10 μM; 5 days) with an inhibition rate of 18.1%[1].
WYC-210 has been evaluated in vitro for its effects on cell growth. At a concentration of 10 μM over 5 days, it inhibited the growth of B16-F1 TRC cells, with an inhibition rate of 18.1%. This low level of activity is consistent with its description as a compound with lower anticancer properties. Its primary in vitro utility is as a chemical probe or a building block for more complex molecules via click chemistry.
ln Vivo
In vivo data for WYC-210 are not available in the public domain. As a research compound with lower biological activity, it is likely used primarily as a negative control or for chemical biology applications rather than for therapeutic efficacy studies in animal models.
Enzyme Assay
Non-cell-based assays for WYC-210 are not typically performed to assess biological activity, as it is not a primary drug candidate. Its characterization involves standard analytical chemistry methods to confirm its structure and purity. This includes High-Performance Liquid Chromatography (HPLC), Nuclear Magnetic Resonance (NMR) spectroscopy, and Mass Spectrometry (MS). Its utility as a click chemistry reagent is verified by demonstrating its ability to undergo CuAAc reactions.
Cell Assay
Cell-based assays for WYC-210 have been conducted to assess its anticancer activity. In one study, B16-F1 TRC cells were treated with WYC-210 at a concentration of 10 μM for 5 days, and cell growth inhibition was measured, yielding an inhibition rate of 18.1%. This assay is typically performed to compare its activity against more potent retinoids like Tazarotene.
Animal Protocol
In vivo animal studies for WYC-210 are not documented in the available literature. Its classification as a compound with lower anticancer activity and primary use as a chemical reagent suggests that it is not intended for efficacy studies in animal models of cancer.
ADME/Pharmacokinetics
WYC-210 has a molecular weight of 340.40 g/mol and the formula C₁₈H₁₆N₂O₃S. It is soluble in DMSO. Its CAS number is 2131803-93-3. As a click chemistry reagent, it contains an alkyne group for CuAAc reactions. The compound should be stored as a powder at -20°C, where it is stable for up to 3 years.
Toxicity/Toxicokinetics
Specific toxicological data for WYC-210 are not available. As a research chemical with low biological activity, it is presumed to have a manageable safety profile for laboratory use. However, standard precautions for handling chemical reagents should be observed, including the use of personal protective equipment.
