ddCTP tetrasodium is a type of chain-terminating deoxynucleotide. ddCTP tetrasodium can be incorporated into the extension primer chain that lacks the 3'-hydroxyl group, thereby terminating primer extension, viral genome replication, and DNA synthesis. ddCTP tetrasodium can distinguish almost identical RNA through distinguishable extension products in primer extension inhibition experiments. ddCTP tetrasodium is the active metabolite of Zalcitabine (HY-17392), which can competitively inhibit HIV reverse transcriptase, terminate the synthesis of viral DNA chains, and thereby inhibit HIV replication.

Cephradine (Standard) is the analytical standard of Cephradine. This product is intended for research and analytical applications. Cephradine (Cefradine) is a broad-spectrum and orally active cephalosporin. Cephradine is active against both gram-positive and gram-negative pathogens. Cephradine is effective in eradicating most penicillinase-producing organisms. Cephradine has been used in the research of genitourinary, gastrointestinal and respiratory tract infections, and in infections of the skin and soft tissues. Cephradine blocks solar-ultraviolet induced skin inflammation through direct inhibition of TOPK.

Neocopiamycin B is found in the strain of Str. hygroscopicus var. crystallogenes. Neocopiamycin B has antifungal activity.

Panosialin wA can inhibit α,β-glucosidase and mannose glycosidase. Panosialin wA does not inhibit the influenza virus, but it has weak anti-microbial effect.

Saframycin E has the effect of anti-Gram-positive bacteria. Saframycin B also has weak activity against mycobacteria.

(Rac)-Xeruborbactam is the racemic form of Xeruborbactam (HY-136069). Xeruborbactam is a potent, ultra-broad-spectrum boronic acid β-lactamase (Beta-lactamase) inhibitor. Xeruborbactam inhibits both serine and metallo-β-lactamases.

Echinocandin B nucleus (A-30912 A nucleus) is the reaction product catalyzed by Echinocandin B (HY-125723) deacylase. Echinocandin B nucleus serves as an intermediate for the synthesis of semi-synthetic antifungal agents.

Fluoxastrobin is a fungicide. By binding to NAD-dependent epimerase/dehydratase, Fluoxastrobin interferes with electron transport, reduces ATP production and inhibits mycelial growth, thereby effectively controlling foliar diseases of tea plants. Fluoxastrobin induces oxidative stress by increasing ROS levels and lipid peroxidation, causes DNA damage and promotes apoptosis; meanwhile, it shows high acute toxicity to Danio rerio embryos and larvae. Fluoxastrobin can be used in research related to tea foliar diseases (including tea red leaf spot and tea gray leaf spot).

Dienomycin A has anti-Gram-positive bacteria and mycobacterium activities.

Destruxin B2 (compound 5) is a natural depsipeptide that can be inhibits hepatitis B surface antigen (HBsAg) secretion in Hep3B cells with an IC₅₀ 1.30 μM.

Calcimycin (Standard) is the analytical standard of Calcimycin. This product is used for research and analytical applications. Calcimycin is an antibiotic and a unique divalent cation ionophore, such as calcium ions and magnesium ions. Calcimycin induces Ca²⁺ -dependent cell death by increasing the intracellular calcium concentration. Calcimycin inhibits the growth of Gram-positive bacteria and some fungi, and also inhibits the activity of ATPase and uncouples the oxidative phosphorylation (OXPHOS) of mammalian cells, inducing apoptosis and autophagy.

Temporin F is an antimicrobial peptide against Legionella pneumophila.

Cephalosporin C analog-1 sodium is an analogue of Cephalosporin C (HY-B1299). Cephalosporin C has weak resistance to Gram-positive and negative bacteria, is stable to penicillinase, and can be broken down by cephalosporin enzyme. Hydrolysis and removal of side chains to obtain 7-amino-cefenoic acid (7-ACA) is an important raw material for the preparation of semi-synthetic cephalosporin.

Menoxymycin A is an antibiotic. Menoxymycin A has a cytotoxic effect. Menoxymycin A inhibits KB and N18-RE-105 cells with IC₅₀s of 0.86 μM and 0.14 μM.

R-1479 (Standard) is the analytical standard of R-1479 (HY-10444). This product is intended for research and analytical applications. R-1479 (4'-Azidocytidine), a nucleoside analogue, is a specific inhibitor of RNA-dependent RNA polymerase (RdRp) of HCV. R-1479 inhibits HCV replication in the HCV subgenomic replicon system (IC₅₀=1.28 μM). R-1479 is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

β-Prumycin hydrochloride is a carbohydrate antibiotic. β-Prumycin hydrochloride has anti-fungal activity and weak anti-individual bacterial activity.

Dealanylalahopcin is an antimicrobial agent that can be isolated from the culture filtrate of Streptomyces leucoderma subsp. ochraceus. Dealanylalahopcin can also be synthesized by enzymatic hydrolysis of alahopcin by microbial α-amino acid ester hydrolases. Dealanylalahopcin has weak antimicrobial activity against Gram-positive and Gram-negative bacteria and exhibits moderate inhibition of collagen prolyl hydroxylase.

Arylomycin A3 is a lipohexapeptide antibiotic against Gram-positive bacteria.

CYP51-IN-2 (compound 1f), a Fluconazole (HY-B0101) analog, is a potent antifungal agent. CYP51-IN-2 shows MIC₈₀s of 62.5 and 15.6 ng/mL for Microsporum gypseum and Candida albicans, respectively.

Simeprevir (Standard) is the analytical standard of Simeprevir (HY-10241). This product is intended for research and analytical applications. Simeprevir (TMC435; TMC435350) is an oral, potent and highly specific hepatitis C virus (HCV) NS3/4A protease inhibitor with a K_i of 0.36 nM. Simeprevir inhibits HCV replication with an EC₅₀ of 7.8 nM. Simeprevir also potently suppresses SARS-CoV-2 replication and synergizes with Remdesivir. Simeprevir inhibits the main protease (Mpro) and the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2, and also modulates host immune responses.
