Lactimidomycin
Based on 1 publication(s) in Google Scholar
Lactimidomycin is a glutarimide-containing compound isolated from Streptomyces. Lactimidomycin is a potent inhibitor of eukaryotic translation elongation. Lactimidomycin has a potent antiproliferative effect on tumor cell lines and selectively inhibit protein translation. Lactimidomycin inhibits protein synthesis with an IC50 value of 37.82 nM. Lactimidomycin is also a potent and non-toxic inhibitor of dengue virus 2 and other RNA viruses. Anticancer and antiviral activities.

In Vitro
Lactimidomycin (0.01-100 nM; 24 hours; Hs 579T, HCC 1937, HCC 1395, HCC 2218, BT 474, MCF 7, MDA MB231 cells and MCF 10A) treatment inhibits cell growth with IC50 concentrations in the low nanomolar range, but higher doses are necessary to inhibit growth of the non-tumorigenic breast cell line MCF10A[1].
Lactimidomycin induces a clear dose-responsive inhibition of DENV2 infectious particle production with an EC90 value of 0.4 μM. No measurable decrease in cell viability was detected at concentrations up to 12.5 µM[2].
Lactimidomycin is a potent inhibitor of DENV2 and Lactimidomycin's inhibition of DENV2 translation leads to reduced production of newly infectious particles. Lactimidomycin may protect cells from viral cytopathic effects including apoptosis, likely through inhibition of virus protein production and replication[2].

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
