Bestatin (Ubenimex) competitively inhibits many aminopeptidases, including B, N and leucine aminopeptidases. Ubenimex is a microbial metabolite and dipeptide with potential immunomodulatory and antitumor activities. Aminopeptidases has been implicated in the process of cell adhesion and invasion of tumor cells. Therefore, inhibiting aminopeptidases may partially attribute to the antitumor effect of ubenimex. This agent also activates T lymphocyte, macrophage, and bone marrow stem cell as well as stimulates the release of interleukin-1 and -2, thus further enhances its antitumor activity.

Tacrolimus monohydrate (LCP-Tacro) is a macrolide from the culture broth of a strain of Streptomyces tsukubaensis, binds to FK506 binding protein (FKBP) to form a complex. Tacrolimus inhibits calcineurin phosphatase, which inhibits T-lymphocyte signal transduction and IL-2 transcription. Immunosuppressive properties. It prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro and has strong immunosuppressive activity in vivo.

Tacrolimus (Fujimycin) can bind FKBP12 to form a high-affinity complex (Ki: 0.2 nM) which inhibits the activity of the calcium calmodulin-dependent protein phosphatase.

Inosine pranobex (Delimmun) has a number of immunomodulatory effects, including inducing T-lymphocyte differentiation, augmenting macrophage and NK cell functions, and stimulating IL-2 production. Through these effects and others, isoprinosine shows antiviral activity and has applications against subacute sclerosing panencephalitis. It also restores depressed immune responses in Y patients after irradiation and reduces the incidence of infection in leukemia patients undergoing chemotherapy. It is most commonly used to treat the rare measles complication subacute sclerosing panencephalitis in conjunction with intrathecal interferon therapy.

Acalabrutinib (ACP-196), also known as ACP-196, is an orally available inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

Lifitegrast (SAR 1118) is an antagonist of lymphocyte function-associated antigen-1.

1. L-Arginine (L-Arg) exhibits anti-atherosclerotic effect. 2. L-Arginine and soy enriched diet are effective in prevention of osteoporosis associated with diabetes mellitus. 3. Exogenous L-Arginine could enhance neonate lymphocyte proliferation through an interleukin-2-independent pathway. 4. A combination of oral L-citrulline and L-Arginine effectively and rapidly augments NO-dependent responses at the acute stage.

A-1211212 (BCL2-IN-1) is a potent and selective Bcl-2 inhibitor. It promotes lymphocyte apoptosis, alters colonic mucosa in mice, and improves inflammation.

NKH477 (Colforsin dapropate hydrochloride) is a derivative of forskolin with antidepressant activity. It inhibits ACh-induced Ca2+ mobilization by acting on ionomycin-sensitive storage sites. NKH477 is an adenylyl cyclase activator with bronchodilatory effects, inhibiting the production of CTL, T-cell proliferation in mixed lymphocyte reactions (MLR), as well as IL-2 production and mitogen responses.

NVP-QAV-680 is a potent and selective antagonist of CRTh2 receptor. NVP-QAV-680 has nM functional potency for inhibition of CRTh2 driven human eosinophil and Th2 lymphocyte activation in vitro.

Ponesimod (ACT-128800) is an orally available sphingosine-1-phosphate receptor 1 (S1PR1, S1P1) agonist with potential immunomodulating activity.

1. Peimisine (Ebeiensine) can affect M-receptor, excit β-receptor, restrain the release of internal calcium, and promote to releaseing nitrogen monoxidum in order to relax tracheal smooth muscle and relieve asthma. 2. Peimisine can attenuate lung tissue injury( ALI), LDH and MDA amount in ALI mice in a dose dependent manner, it also lower the total protein, total white blood cells, lymphocyte and neutrophilic leukocyte in bronchoalveolar lavage fluid( BALF); suggests that peimisine can play a protective role against LPS-induced acute lung injury. 3. Peimisine has the protective effect on the experimental hepatic fibrosis formation, the possible mechanisms are associated with inhibiting fibrogenesis and fibrosis accumulation, and decreasing lipid peroxidation. 4. Peimisine can inhibit angiotensin I converting enzyme activity in a dose-dependent manner, displaying 5 % inhibitory concentration values of 526.5 microM, thus, it may have antihypertensive action.

Aspartyl-alanyl-diketopiperazine acetate (DA-DKP) (DA-DKP) can modulate the inflammatory immune response through a molecular pathway implicated in T- lymphocyte anergy.

AZD8797 (KAND567) is an orally available, selective and potent human CX3CR1-converting antagonist with inhibitory effects on CX3CR1 and CXCR2, and potentially protects against SARS-CoV-2-induced neuronal damage, preventing worsening of nociceptive sensitization and microglial activation in a migraine model of rats following seizures.

BI-1950 is a highly potent inhibitor of lymphocyte function-associated antigen-1 (LFA-1), an essential component in normal immune system function and a significant target for drug discovery [1].

Forodesine (BCX-1777) is an orally active and potent purine nucleoside phosphorylase (PNP) inhibitor, a new purine nucleoside analog, inhibitor of human lymphocyte proliferation, induces apoptosis in leukemic cells by increasing dGTP levels, and may be useful in the study of cutaneous T-cell lymphomas.
