From Virtual Hits to Validated Leads—Integrated Synthesis and Validation Support
Virtual screening and computational modeling identify promising candidate molecules, but translating computational predictions into experimentally validated leads requires high-quality synthetic chemistry and rigorous biochemical validation. The gap between in silico prediction and in vitro confirmation is one of the most critical bottlenecks in early-stage drug discovery, where compound availability, synthetic tractability, and assay-ready quality determine project velocity.
At Profacgen, our Lead Validation & Synthesis Support platform bridges this gap by providing custom synthesis of peptides and small molecules, followed by comprehensive biochemical and biophysical validation. Our integrated approach ensures that computational hypotheses are rapidly tested with high-confidence experimental data, enabling informed decisions on lead progression and structural optimization.
Profacgen offers two complementary synthesis and validation tracks tailored to the distinct requirements of peptide therapeutics and small-molecule drug candidates:
High-quality custom peptide synthesis using solid-phase (SPPS) and solution-phase methodologies, supporting sequences from 5 to 100+ residues with diverse modifications including phosphorylation, acetylation, fluorescent labeling, cyclization, and non-natural amino acid incorporation. Our platform delivers research-grade to GMP-grade peptides with rigorous purity assessment by HPLC and mass spectrometry, enabling structure-activity relationship studies, epitope mapping, and therapeutic peptide development.
Custom synthesis of small-molecule drug candidates and lead compounds, from milligram to multi-gram scales, using route design, retrosynthetic analysis, and established synthetic methodologies. Our medicinal chemistry team supports hit validation, SAR exploration, analog library preparation, and scaffold hopping, delivering compounds with full analytical characterization (NMR, LC-MS, HRMS) suitable for biochemical assays, cell-based screening, and in vivo studies.
Beyond synthesis, Profacgen provides end-to-end lead validation support that connects compound generation with functional characterization:
This closed-loop workflow — from computational design through custom synthesis to experimental validation — dramatically shortens design-make-test-analyze cycles and improves the quality of lead candidates advancing into preclinical development.
