CHIKV-IN-2, a chemical compound, exhibits potent inhibitory activity against the enzyme Dihydroorotate Dehydrogenase (DHODH), crucial for pyrimidine synthesis affecting various viruses' replication. It serves as an effective Chikungunya virus (CHIKV) inhibitor, demonstrating significant cellular antiviral activity (EC90=270 nM) and enhanced liver microsomal stability[1].

Cletoquine is a major active metabolite of Hydroxychloroquine. Cletoquine has the ability to against the chikungunya virus (CHIKV). Cletoquine has antimalarial effects and has the potential for autoimmune disease treatment.

beta-Amyrone (β-Amyron) has antifungal activity against Chikungunya virus replication with an EC50 of 86 uM. beta-Amyrone has anti-inflammatory activity through inhibiting the expression of COX-2. beta-Amyrone exhibits anti-α-glucosidase inhibitory activity and moderate AChE activity. β-Amyrone can be used in the research of disease like inflammation, infection, and obesity.

CHIKV nsP2 protease-IN-1 (compound J13) is an orally active inhibitor of non-structural protein 2 protease (non-structural protein 2protease), exhibiting an EC50 value of 0.39 μM against CH S27. This compound is utilized in the research of Chikungunya virus.

CHIKV-IN-5 (Compound 26) is an inhibitor of CHIKV with an EC90 value of 0.45 μM. It suppresses the replication of CHIKV in the later stages of the viral life cycle by blocking the translation of structural proteins. CHIKV-IN-5 demonstrates high stability in vitro within mouse microsomes. In infected mice, it alleviates footpad swelling and reduces the spread of the virus to other tissues.

CHIKV-IN-3 is a potent inhibitor effective against two low-passage CHIKV strains, with EC50 values of 1.55 μM for CHIKV-122508 and 0.14 μM for CHIKV-6708, respectively. It targets host cells to disrupt viral replication while maintaining minimal cytotoxic liability (CC50 > 100 μM). Additionally, CHIKV-IN-3 has shown a prophylactic effect [1].

CHIKV-IN-4 (compound 31b) acts as a potent and selective inhibitor of the Chikungunya virus, displaying an EC50 value of 0.6 μM [1].

EIDD-1931 (Beta-d-N4-hydroxycytidine) is a ribonucleoside analog with antiviral activity that inhibits the replication of severe acute respiratory syndrome coronavirus [SARS-CoV] in Vero 76 cells, Middle East respiratory syndrome coronavirus [MERS-CoV] in Calu-3 2B4 cells, and SARS-CoV-2 in Vero cells (IC50s = 0.1, 0.15, and 0.3 μM, respectively).

Cletoquine hydrochloride is a major active metabolite of Hydroxychloroquine. Cletoquine hydrochloride is a Chloroquine derivative and exhibits the ability to against the chikungunya virus (CHIKV). Cletoquine hydrochloride exhibits antimalarial effects.

Cletoquine oxalate (Desethylhydroxychloroquine oxalate) is a major active metabolite of Hydroxychloroquine, with antiviral efficacy against the chikungunya virus (CHIKV), antimalarial effects, and potential for treating autoimmune diseases.

nsP2 Protease-IN-1 is a potent irreversible covalent inhibitor of the nsP2 cysteine protease of the Chikungunya (CHIKV) virus, exhibiting an IC50 of 60 nM. This compound demonstrates strong antiviral activity by inhibiting the replication of CHIKV and Venezuelan equine encephalitis virus (VEEV), with EC50 values of 0.01 µM and 0.3 µM, respectively.

NHC-diphosphate, a phosphorylated intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) in its diphosphate form[1], serves as a potent antiviral agent. As a pyrimidine ribonucleoside, NHC effectively counters the replication of Venezuelan equine encephalitis virus (VEEV), Chikungunya virus (CHIKV), and hepatitis C virus (HCV)[1].

Tat-beclin 1, a peptide derived from the autophagy protein beclin 1, is a powerful inducer of autophagy. It interacts with GAPR-1 (GLIPR2), a negative regulator of autophagy. Tat-beclin 1 effectively reduces polyglutamine expansion protein aggregates and inhibits various pathogens, such as HIV-1, in laboratory experiments. Additionally, it decreases mortality in mice infected with chikungunya (CHIKV) or West Nile virus (WNV).

Tat-beclin 1 TFA, a peptide derived from a segment of the autophagy protein beclin 1, effectively induces autophagy and interacts with the autophagy negative regulator GAPR-1 (GLIPR2). It reduces the accumulation of polyglutamine expansion protein aggregates and limits the in vitro replication of various pathogens, including HIV-1. Additionally, Tat-beclin 1 TFA has been shown to decrease mortality rates in mice infected with chikungunya (CHIKV) or West Nile virus (WNV) [1].

Harringtonine is a naturally occurring alkaloid that inhibits DNA synthesis and protein synthesis and strongly kills S-phase cells. Harringtonine has antitumor and antiviral activities.

DDABT1 exhibits anti-CHIKV activity (IC50 of 14.53 μM) and possesses anti-inflammatory and anti-arthritic properties [1].
