Lydimycin

(Synonyms: α-DHB; α-Dehydrobiotin)

Lydimycin (α-DHB; α-Dehydrobiotin) is an antibiotic produced by Streptomyces lydicus, with antibacterial, antifungal and antiviral activities. Lydimycin inhibits the binding of SARS-CoV-2 S-614G spike protein to human ACE2. The antibacterial activity of Lydimycin can be reversed by Biotin (HY-B0511) in the culture medium. Lydimycin is applicable to infection-related research.

Description

IC₅₀ & Target

Bacterial^[1]

All Antibiotic Isoforms :

In Vitro

Lydimycin (compound Ⅰ) displays broad-spectrum in vitro antimicrobial activity against diverse gram-positive bacteria, gram-negative bacteria, and fungi^[1].
Lydimycin (1.25-20.0 μg) inhibits Escherichia coli growth in a synthetic medium in a dose-dependent manner, with its antibacterial activity reversed by increasing concentrations of biotin, showing no inhibition at 0.100 μg/mL Biotin (HY-B0511) across all tested doses^[1].
Lydimycin (0-200 μM) inhibits the binding of SARS-CoV-2 S-614G-Strep spike protein to human ACE2-Fc with an IC₅₀ of 1.6 μM, without non-specific Alpha signal interference^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
