HY-W440896

DSPE-PEG-SH, MW 2000	Liposome	Others
DSPE-PEG-SH, MW 2000 is a pegylated phospholipid with thiol group which is reactive with maleimide to form a covalent thioether linkage. The amphiphatic polymer can form lipid bilayer in aqueous solution and be used to encapsulate agents for drug delivery system, such as mRNA vaccine.

HY-48999A

FSK hydrochloride	Others	Cancer
FSK hydrochloride is fluorosulfonyloxybenzoyl-l-lysine, with a long and flexible aryl fluorosulfate-containing side chain that can reach protein sites that are difficult to reach by covalent linkage. FSK hydrochloride is a modified nanomolecule that targets the epidermal growth factor receptor (EGFR), creating a covalent binding that results in irreversible binding. FSK hydrochloride captures unknown enzyme-substrate interactions in living cells through genetically encoded chemical cross-linking, targeting residues beyond Cys, and cross-linking at the binding periphery. FSK hydrochloride enables the construction of bioreactive SuFEx systems for creating covalent bonds in different proteins in vitro and in vivo .

HY-145823

EGFR-IN-42	EGFR	Cancer
EGFR-IN-42 (Compound 17b) is a potent inhibitor of EGFR with single-digit nanomolar activity. EGFR-IN-42 connects tamoxifen or endoxifen with the EGFR-inhibitor gefitinib via a covalent linkage. EGFR-IN-42 retains both ER antagonist activity and EGFR inhibition. EGFR-IN-42 has superior anti-cancer activity .

HY-145824

EGFR-IN-43	EGFR	Cancer
EGFR-IN-43 (Compound 17c) is a potent inhibitor of EGFR with single-digit nanomolar activity. EGFR-IN-43 connects tamoxifen or endoxifen with the EGFR-inhibitor gefitinib via a covalent linkage. EGFR-IN-43 retains both ER antagonist activity and EGFR inhibition. EGFR-IN-43 has superior anti-cancer activity .

HY-118112

4-N-Maleimidobenzoicacid-NHS	Biochemical Assay Reagents	Others
4-N-Maleimidobenzoicacid-NHS is a PEG linker that finds utility in bioconjugation endeavors and protein labeling ventures. Specifically designed for selective reaction with thiol groups, the maleimide group establishes covalent linkages, thereby facilitating the coupling of proteins, peptides, or diverse molecules to thiol-bearing biomolecules. The NHS ester is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic conditions to form a covalent bond.

HY-W591360

Iodoacetamido-PEG6-azide	Biochemical Assay Reagents	Others
Iodoacetamido-PEG6-azide is an aqueous soluble PEG linker containing an azide and a terminal Iodoacetamido group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Iodoacetamido moiety is commonly used to bind covalently with the thiol group of cysteine so the protein cannot form disulfide bonds.

HY-D2744

BP Fluor 488 TCO	Fluorescent Dye	Others
BP Fluor 488 TCO reacts with tetrazines to produce a stable, covalent linkage, also referred to as the inverse-electron demand Diels-Alder cycloaddition reaction. This reaction is extremely fast (k > 800 M-1 s-1), selective, biocompatible, and does not require Cu-catalyst or elevated temperatures. Such excellent reaction rate constants are unparalleled by any other bioorthogonal reaction pair described to date.

HY-W800670

Mal-amido-PEG5-alkyne	Biochemical Assay Reagents	Others
Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

HY-144323

YF135	PROTACs PERK	Cancer
YF135 is an efficient and reversible-covalent KRAS ^G12C PROTAC. YF135 is designed and synthesized by tethering KRAS G12C inhibitor 48 (compound 6d) as the ligand, and basing on the scaffold of MRTX849 linkage VHL ligand. YF135 significantly induces the degradation of KRAS ^G12C in a reversible manner and decreases phospho-ERK level through the E3 ligase VHL mediated proteasome pathway .

HY-W591390

6-Azidohexanoic acid STP ester	Biochemical Assay Reagents	Others
6-Azidohexanoic Acid STP Ester is an amine-reactive, water-soluble labeling reagent with an azide group and a terminal 4-Sulfo-2,3,5,6-tetrafluorophenyl (STP) group. 6-Azidohexanoic Acid STP Ester is used to modify proteins, antibodies, and other amine-containing biopolymers in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. STP esters can react with primary amines, forming covalent amide bonds, and typically display much better stability toward hydrolysis in aqueous media, resulting in more efficiency and better reproducible labeling of biopolymers.
