LP533401 (LP-533401) is a novel and potent inhibitor of tryptophan hydroxylase 1 with the potential for the treatment for osteoporosis. It is able tp regulate serotonin production in the gut.
| ln Vitro |
At a dosage of 1 μM, LP-533401 totally suppresses the synthesis of serotonin in Tph1-expressing cells (RBL2H3 cells)[1].

| ln Vivo |
Due to a distinct increase in bone production, oral administration of this small molecule once daily for up to 6 weeks completely rescues and prevents the onset of osteoporosis in ovariectomized rodents in a dose-dependent way. After oral treatment, LP-533401 levels in the brain are insignificant, according to pharmacokinetic tests conducted on mice, suggesting that it is essentially unable to penetrate the blood-brain barrier[1]. Repeated administration of LP-533401 (30–250 mg/kg per day) to mice results in significant decreases in 5-HT levels in the blood, lungs, and stomach but not in the brain. Lung and gut 5-HT contents drop by 50% following a single LP533401 dose (250 mg/kg), while blood 5-HT levels stay constant, indicating gut and lung 5-HT synthesis[2]. When administered with the Tph-1 inhibitor LP-533401, adult, healthy mice exhibit a 30% drop in serotonin levels in the blood, which is followed by a 30% increase in osteoblast counts. Giving LP533401 to mice that have received an EL4 cell injection prevents the loss in trabecular bone volume and osteoblast counts, prolongs survival, and lowers leukemic infiltration[3].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
