Background: Inflammation plays a key role in the progression of many chronic diseases. As country with rich biodiversity, Indonesia offers numerous phytochemicals potential for drug development, including catechin, natural compound anti-inflammatory properties. Objective: This study aimed to identify targets catechin and evaluate its inhibitory potency through molecular docking simulations. Methods: Data acquisition refinement were conducted using NCBI, STRING, STITCH databases, intersections identified Venn diagrams. Molecular was performed AutoDockTools 1.5.6, interactions visualized BIOVIA Discovery Studio. Results: Bioinformatics analysis predicted that inhibits three pro-inflammatory proteins: COX-2, HSP90, IL-2. Catechin’s indicated by negative binding energies amino acid residues critical target protein activity. Among targets, IL-2 exhibited lowest energy (-5.12 kcal/mol), suggesting it as primary target. However, catechin’s affinity lower than native ligand (-11.78 kcal/mol). Conclusion: is be Structural modifications are recommended enhance therapeutic potential.

Atopic dermatitis (AD) is prone to exacerbations in response various triggering factors and flare-ups after remission. We searched for molecules associated with relapse/exacerbation of AD among altered gene expression the skin patients AD. Microarray analyses were performed on lesional non-lesional adolescent or adult recalcitrant healthy controls. Five chaperones involved intracellular stress responses, namely heat shock protein family A (Hsp70) member 9 (HSPA9), 90 beta 1 (HSP90B1), calnexin (CANX), malectin (MLEC; endoplasmic reticulum-associated degradation), D (Hsp60) (HSPD1), consistently upregulated uninvolved Damage-associated molecular patterns skin. KLF transcription factor 2 (KLF2) was decreased exhibited a decreasing trend CD4(+)/CD8(+) double-positive cells (1.4% T cells) detected lesions declined KLF2 levels. WNT inhibitory (WIF1) downregulated Prolactin-induced only found increased responses Multifactorial genetic diseases, such as asthma, inflammatory bowel disease, type diabetes, rheumatoid arthritis, are stress. Intracellular abnormalities may also be responsible Further research incorporate enhanced into mechanism underlying

The inhibition of heat shock protein 90 (HSP90), a molecular chaperone, has been proposed to be potential novel treatment strategy for Coronavirus disease 2019 (COVID-19). In contrast other studies, our data demonstrated that RGRN-305, HSP90 inhibitor, exacerbated the cytopathic effect and did not reduce viral shedding in VeroE6-hTMPRSS2 cells infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Likewise murine model SARS-CoV-2, transgenic mice treated orally RGRN-305 exhibited reduced survival by end experiment (day 12) as 14% (1/7) survived compared 63% (5/8) those drug-vehicle. Animal weight was treatment. Interestingly, we significantly dampened inflammatory response induced SARS-CoV-2 spike human macrophage-like (U937) lung epithelial (A549). Measured quantitative real-time PCR, mRNA expression proinflammatory cytokines TNF , IL1B IL6 were reduced. Together, these suggest exacerbates infection vitro reduces but exhibits strong anti-inflammatory properties. This shows while may helpful ‘cytokine storm’, it no beneficial impact on replication or animals monotherapy. Further animal studies inhibitors combination an anti-viral drug provide additional insights into its utility infections whether continue COVID-19 disease.
