Semisynthesis

Semisynthesis


Panlabs utilizes microbial fermentation and enzymatic conversion technologies to produce precursors or intermediates of target compounds, which are then further refined through chemical synthesis to obtain the final products. Compared to traditional full chemical synthesis, this approach reduces the number of reaction steps and the use of organic solvents, thereby minimizing environmental impact. Panlabs provides gram-scale process optimization and supports customers in scaling up to commercial production, streamlining the overall workflow, reducing production costs, and enhancing efficiency and product quality.

OUR CASE
FR901379 → FR179642
FR179642 is a key intermediate in the synthesis of Micafungin, an Echinocandin-like antifungal drug that exerts its effects by inhibiting β-(1,3)-D-glucan synthesis, thereby compromising fungal cell wall integrity.
FR901379 → FR179642
Ansamitocin P-3 (AP3) → Mertansine (DM1)
Mertansine (DM1) is the payload of antibody-drug conjugates (ADCs), a class of targeted cancer therapeutics. It delivers mertansine to tumor cells via antibody binding, releasing the toxin intracellularly to inhibit cell division and induce apoptosis.
Ansamitosin P3 (AP3) →  Mertansine (DM1)
Staurosporine → Midostaurin
Midostaurin is a novel therapeutic agent derived from staurosporine, originally isolated from marine organisms. It acts as a multi-target kinase inhibitor, blocking the action of numerous receptor tyrosine kinases and disrupting signaling pathways essential for cell proliferation. Consequently, midostaurin exerts its anticancer effects by suppressing tumor growth or inducing apoptosis.
Staurosporine → Midostaurin
Calicheamicin γI → N-Acetyl-Calicheamicin
N-Acetyl-Calicheamicin is a highly potent cytotoxic agent belonging to the enediyne class of antibiotics. It exerts its antitumor activity by binding to DNA and inducing double-strand breaks, ultimately triggering apoptosis. Due to its high potency, N-Acetyl-Calicheamicin is primarily used as a payload in antibody-drug conjugates (ADCs) for targeted cancer therapy.
