Component
Shikimic acid
A nonaromatic plant and microbial metabolite connecting chorismate biosynthesis, cofactor requirements, microbial vitamin precursors and context-specific mammalian experimental responses.
64 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

**One chemical scaffold, two protonation states.** Shikimic acid is (3R,4S,5R)-3,4,5-trihydroxycyclohex-1-ene-1-carboxylic acid, C7H10O5, molecular mass 174.15 g/mol. Its ring is not aromatic, so calling it a phenolic compound is chemically misleading even when a paper does so. Shikimate is its carboxylate conjugate base (C7H9O5−); charge is meaningful, but these must remain connected identities. Neither is oseltamivir, anisatin, triacetylshikimic acid or 3,4-O-isopropylidene shikimic acid. Plants and many microorganisms use the biosynthetic pathway; humans have no complete endogenous shikimate pathway. Absence of that pathway does not mean an ingested molecule cannot be absorbed or metabolized by the host–microbiome system.

**Gut metabolism and host conjugation must be distinguished.** The 1978 rat study traced oral shikimic acid into urinary hippurate, hexahydrohippurate, tetrahydrohippurate, two dihydroxycyclohexanecarboxylate isomers, catechol conjugates and expired CO2. Antibiotic treatment suppressed the characteristic conversion, implicating initial gut-microbial transformations. Host metabolism of microbial products still occurs. Hippurate contains a glycine conjugate, but product detection does not establish clinically significant glycine depletion or an identical human quantitative pathway. No assertion that parent shikimic acid is directly converted to every final product in one reaction is made. [The metabolism of shikimate in the rat.](https://pubmed.ncbi.nlm.nih.gov/637841/)

**Hair-follicle findings include human tissue, not a human treatment trial.** In isolated human hair follicles, 1 or 10 µM shikimic acid increased shaft elongation during 12-day culture. Dermal papilla cells showed higher MTT readouts, and 1 µM exposure increased MYC, HGF, KGF and VEGF transcripts at 24 h and p38/CREB phosphorylation at 15 min. Transcript increases are not proof of increased secreted growth-factor flux. Mannose-receptor staining establishes receptor presence, not that this receptor was necessary for the response. Topical 10–100 mM exposure also affected anagen-related measurements in mice; neither system establishes oral human hair regrowth.

**Mouse distribution and bounded toxicity observations.** The 2025 mouse study reported intravenous half-lives approximately 0.76–0.85 h at 4–16 mg/kg and oral bioavailability approximately 11.09–20.44% at 50–100 mg/kg. A short plasma half-life does not prove unchanged renal excretion. In a separate 28-day feeding experiment, dietary concentrations were 5.56, 16.67 and 50 g/kg FEED, not mg/kg body weight. High-dose animals had small hematological shifts and lower triglycerides; acute survival through tested doses is not evidence of lifetime human safety. No validated human monocarboxylate-transporter assignment was found in the reviewed sources.

**Oligodendrocyte differentiation differs from proliferation.** In primary rat oligodendrocyte precursor cultures, shikimic acid at 1–100 µg/mL increased MBP-associated differentiation after 72 h, with 100 µg/mL used for subsequent experiments. That highest concentration is calculated as about 574 µM. BrdU incorporation and TUNEL readouts did not significantly change. Increased MBP and fewer NG2-positive cells therefore support maturation in this model, not universal stimulation of cell proliferation.

**Perturbations expose a conditional signaling route.** In those rat precursor cultures, rapamycin blocked the shikimic-acid-associated rise in MBP, while the MEK inhibitor U0126 did not abolish it. PI3K inhibitors wortmannin and LY294002 reduced the elevated mTOR-phosphorylation readout toward control. These are joint experimental contrasts supporting pathway dependence; they do not establish that shikimic acid binds mTOR or that all MEK activity is irrelevant.

**Human blood was exposed outside the body.** Veach 2016 added 0.1–2 mM shikimic acid to blood from 22 sedentary participants. ADP-induced aggregation decreased at 2 mM, whereas collagen-induced aggregation did not significantly decrease. Flow cytometry recorded lower PAC-1 signal at 2 mM, CD62P at 1–2 mM, monocyte–platelet aggregates at 0.5–2 mM and CD31 at 1 mM. PAC-1 here is a platelet activation assay label; the abstract’s expansion as a procaspase-activating compound is not imported as a drug mechanism.

**Oligodendrocyte differentiation differs from proliferation.** In primary rat oligodendrocyte precursor cultures, shikimic acid at 1–100 µg/mL increased MBP-associated differentiation after 72 h, with 100 µg/mL used for subsequent experiments. That highest concentration is calculated as about 574 µM. BrdU incorporation and TUNEL readouts did not significantly change.

**Star-anise toxicity is a preparation-identity issue.** Anisatin inhibited GABA-activated currents in rat dorsal-root-ganglion neurons in a use-dependent fashion; an estimated EC50 was 1.10 µM. It is a different molecule from shikimic acid. Seven infant neurological cases associated with star-anise tea and evidence of toxic species contamination demonstrate preparation risk, not toxicity attributable specifically to purified shikimic acid. Botanical identity, plant part, contamination, extraction and measured composition cannot be inferred from the name star anise.

**Derivatives keep their own outcomes.** Triacetylshikimic acid (TSA) reduced stimulated platelet aggregation and shunt thrombosis in rat experiments; reported cAMP increased, while cGMP, thromboxane/prostacyclin metabolites and clotting-time endpoints included null results. Those results are not assigned to parent shikimic acid. The separately tested 3,4-O-isopropylidene derivative (ISA) has rodent inflammatory/pain studies and cell-free radical-scavenging assays.

**A manufacturing precursor is not the finished drug.** Shikimic acid has served as a starting scaffold for chemical manufacture of oseltamivir. Adding the drug’s other functional groups requires chemical synthesis; humans do not turn ingested shikimic acid into oseltamivir. Manufacturing and fermentation routes are industrial context, not antiviral evidence for shikimic acid. The 1997 neuraminidase-inhibitor chemistry paper and the 1998 practical synthesis report concern synthesized drug structures.

**A mixed patch does not isolate shikimic acid efficacy.** The same report studied patches containing 0.5% shikimic acid and 0.5% P. mume extract plus additional formulation constituents in 15 volunteers aged 18–28. It was open-label, nonrandomized and split-body, over 48 h. Sebum decreased with both this patch and a 0.5% salicylic-acid comparator; the between-patch difference was not significant (p=0.12). No adverse skin effects were reported in this small short study. It does not establish isolated shikimic acid efficacy, long-term safety, oral antiandrogen action or synergy.

**AKT and Nrf2 involvement does not identify the binding target.** BV2 experiments recorded increased AKT phosphorylation and nuclear Nrf2. MK2206 pretreatment attenuated Nrf2 activation and partially reversed redox/nitrite responses. A reagent labeled RA also attenuated the Nrf2 response; its identity and selectivity are not independently resolved here, so no vitamin-A or retinoic-acid interaction is created from that abbreviation. Pharmacological perturbation supports pathway involvement while leaving the initiating target and off-target alternatives open.

**A 2026 topical study measured protein amount.** Human sebocytes challenged with 10 nM testosterone were exposed for 72 h to shikimic acid or a 1:1 shikimic-acid/Prunus mume extract mixture. At 0.03 wt%, the mixture lowered the reported type-I 5α-reductase ELISA signal more than shikimic acid alone. The assay measured protein amount in processed supernatant, with three technical replicates and no total-protein normalization; it was not a testosterone-to-DHT catalytic assay. Docking is not measured affinity. Thus a direct 5α-reductase inhibition claim is not justified by this experiment.
