Data Source

Insider transactions sourced from SEC EDGAR Form 4 filings, normalized within minutes of acceptance. "Buy"/"Sell" mark open-market transactions (codes P/S), the tradeable signal. Awards, option exercises and tax-withholding are shown with their raw code. All data is public domain.

Issuer: Synthetic Biologics, Inc., SEC CIK 0000894158. The symbol on a Form 4 is typed by the filer, so this page follows the issuer with the newest filing under SYN and shows every filing by that issuer (also filed as TOVX, AEN, PP, PPEX, PPXP, OTCBB:SFPH, SFPH).

Coverage: Form 4 filings indexed 2006-01-02 → 2026-09-12. Earlier history is backfilling; this window widens as it deepens.

Programmatic access via the Arkolith API & MCP server (insider.transactions, insider.company).
