HSPMdb

HSPMdb compiles experimentally validated modulators of five major heat shock proteins (Hsp100, Hsp90, Hsp70, Hsp60, Hsp40) to support analysis of chaperone modulation and computational drug-design research.

Key Features:

• Scope: 10,223 entries of activators and inhibitors compiled from 176 research articles.
• Hsp coverage: Data cover Hsp100, Hsp90, Hsp70, Hsp60, and Hsp40.
• Organism coverage: Entries derive from studies in human, yeast, bacteria, virus, mouse, rat, bovine, porcine, canine, chicken, Trypanosoma brucei, and Plasmodium falciparum.
• Biological activity fields: Enzymatic parameters include IC50, EC50, DC50, Ki, and KD; cellular parameters include percentage cell growth inhibition, EC50, GI50, assay types, and cell lines.
• Compound classification: Records annotate compounds as activators or inhibitors of Hsp activities.
• Curation: Manually curated compilation of experimentally validated data.
• Similarity screening: Provides compound similarity screening against known Hsp modulators.
• In silico support: Facilitates design of novel inhibitors and scaffolds using in silico prediction algorithms.

Scientific Applications:

• Chaperone biology: Enable analysis of Hsp modulation and mechanistic studies of protein folding, trafficking, and signaling.
• Drug discovery: Support identification and prioritization of Hsp-targeting inhibitors and activators for therapeutic development.
• Cross-species analysis: Compare modulatory effects across organisms including pathogens such as Trypanosoma brucei and Plasmodium falciparum.
• Compound prioritization: Use similarity screening and annotated activity data to prioritize compounds for follow-up cellular and enzymatic assays.

Methodology:

Provides similarity-based compound screening and supports in silico prediction algorithms for the design of novel inhibitors and scaffolds.
