KY-02327, a metabolically stabilized analog of KY-02061, serves as a potent inhibitor of the Dishevelled (Dvl)-CXXC5 interaction. This compound activates the Wnt/β-catenin pathway, thereby promoting osteoblast differentiation.

4-IPP (4-Iodo-6-phenylpyrimidine) is an irreversible inhibitor of macrophage migration inhibitory factor (MIF).

NDMC101 is an inhibitor of dipeptidyl peptidase-IV activity in human T cells and exhibits immunomodulatory effects. It also acts as a novel inhibitor of NFATc1 and NF-κB activity.

Toddaculine may be beneficial for the prevention and treatment of osteoporosis, it can not only inhibit the differentiation of osteoclasts via activation of the NF-κB, ERK 1/2, and p38 MAPK signaling pathways, but can induce differentiation and mineralization of osteoblasts by regulating differentiation factors. Toddaculine also may serve as a pharmacological prototype for the development of novel anti-leukemic agents, it displays a dual effect as a cell differentiating agent and apoptosis inducer in U-937 cells.

Osteoblast-Adhesive Peptide, a polypeptide designed for biomaterials' chemical modification, enhances osteoblast adhesion, showing promise for use in dentistry and orthopedics [1] [2].

Osteoblast-Adhesive Peptide (Lys-Arg-Ser-Arg) acetate is an adhesion peptide utilized as a dental or orthopedic biomaterial to facilitate and strengthen the attachment of osteoblasts (anchor-dependent cells). Osteoblast adhesion is mediated through integrin and proteoglycan mechanisms. This peptide acetate may exhibit specificity for osteoblasts or bone cells in the proteoglycan-mediated adhesion process.

Rifampicin (Rifamycin AMP) is a broad-spectrum antibiotic. Rifampicin has a strong antibacterial effect against Mycobacterium tuberculosis and is also effective against gram-positive and gram-negative bacteria and viruses.

Tetracycline is an orally active broad-spectrum antibiotic that exhibits inhibitory activity against various Gram-positive and Gram-negative bacteria, as well as Chlamydia, Mycoplasma, and Rickettsia. It is commonly used in anti-infection research and can also be used to induce tumor regression based on BCR-ABL gene silencing.

Isopsoralenoside shows estrogen-like, osteoblastic proliferation accelerating, antitumor, and antibacterial effects.

Smoothened (Smo) receptor agonist

Tigogenin is one of steroidal sapogenins which is widely used for synthesizing steroid drugs. It might have protective effect on bone and be helpful in preventing the development of osteoporosis.

Wnt/β-catenin agonist 3 is a Wnt/beta-catenin agonist.

Psoralenoside is a natural product isolated from the fruits of Psoralea corylifolia, shows estrogen-like activity, osteoblastic proliferation accelerating activity, antitumor effects and antibacterial activity.

DIPQUO hydrochloride is an activator of the bone marker alkaline phosphatase (ALP), with an EC50 of 6.27 μM in C2C12 cells. DIPQUO hydrochloride promotes mouse and human osteoblast differentiation via activation of p38 MAPK-β.

Muramyl dipeptide (MDP) is a synthetic immunoreactive peptide, consisting of N-acetyl muramic acid attached to a short amino acid chain of L-Ala-D-isoGln. It indirectly decreases osteoclast differentiation by reducing the RANKL/OPG ratio and directly increases osteoblast differentiation by up-regulating Runx2 gene expression through MAPK pathways, thereby inducing bone formation via Runx2.

ER-50891 is a potent retinoic acid receptor alpha (RARα) antagonist. er-50891 reduces the inhibitory effect of allosteric retinoic acid and restores osteoblast differentiation induced by bone morphogenetic protein 2.

N-Oleoyl-L-Serine (N-Oleoylserine) is an endogenous long-chain fatty acid amide that is a lipid modulator of bone remodeling and stimulates osteoclast apoptosis which can be used to study osteoporosis. N-Oleoyl-L-Serine showed high activity in an osteoblast proliferation assay.N-Oleoyl-L-Serine promotes osteoclast apoptosis by inhibiting Erk1/2 phosphorylation and expression of nuclear κB ligand (RANKL) receptor activator in bone marrow stromal cells and osteoblasts, which attenuates osteoclast populations.

3-Carene(Delta-3-Carene) is a bicyclic monoterpene extracted from western larch and Douglas-fir that acts as a phytofungicide.3-Carene inhibits inflammatory infiltrates and COX-2 overexpression induced by nociceptive stimuli.3-Carene has anti-injury properties and promotes the activity and expression of alkaline phosphatase, an early marker of osteoblast differentiation.

Osthole (Osthol), a potential inhibitor of histamine H1 receptor, has been shown to stimulate osteoblast proliferation and differentiation.

β-Glycerophosphate is a classical serine-threonine phosphatase inhibitor used in kinase reaction buffers. BGP is often used in combination with other phosphatase/protease inhibitors for broad spectrum inhibition. It functions as an organic phosphate donor

JNJ-28330835 is a non-steroidal, oral selective androgen receptor modulator (SARM). In assays using androgen-responsive cells, JNJ-28330835 exhibits both agonist and antagonist activity. JNJ-28330835 acts as an agonist for markers of both osteoclast and osteoblast activity, thereby reducing bone turnover.

(+)-Medicarpin, a pterocarpan, is an isoflavonoid compound derived from medicinal plant species such as Sophora japonica, Zollernia paraensis, Platymiscium yucatamun, Machaerium aristulatum, and Platymiscium floribundum. It potently inhibits osteoclastogenesis and facilitates bone healing and increased bone mass through osteoblast differentiation, mediated by the estrogen receptor (ER) β.

Azadirachtin B (Deacetylazadirachtinol) is a terpenoid compound isolated from Azadirachta seeds, with insecticidal, anticancer, anti-inflammatory, antitumor, and antiviral activities, useful in the study of viral infections. Azadirachtin B also has osteoblast proliferation, differentiation, and mineralization properties.
