Foscarnet sodium (Phosphonoformate) is an antiviral agent used in the treatment of cytomegalovirus retinitis. Foscarnet also shows activity against human herpesviruses and HIV.

Ganciclovir (2'-Nor-2'-deoxyguanosine) is an ACYCLOVIR analog that is a potent inhibitor of the Herpesvirus family including cytomegalovirus. Ganciclovir is used to treat complications from AIDS-associated cytomegalovirus infections.

Floxuridine (FUDR) is an antimetabolite, floxuridine inhibits thymidylate synthase, resulting in disruption of DNA synthesis and cytotoxicity.

Acyclovir (Aciclovir) is a synthetic analog of the purine nucleoside, guanosine, with potent antiviral activity against herpes simplex viruses type 1 and 2, varicella-zoster virus and other viruses of the herpesvirus family.

Isosteviol ((-)-Isosteviol), a common natural sweetener, belongs to tetracyclic diterpene glycosides. The pharmacology researches have suggested that stevioside and its hydrolysis products, steviol, isosteviol and steviolbioside, have many biological activities, such as reducing blood glucose, lowering blood pressure, anti-inflammation, anti-tumor, anti-diarrhea, antibacterium, immunoregulation, etc.

BMH-21, a small molecule DNA intercalator, binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription and not affects phosphorylation of H2AX.

Clevudine (Levovir) is a synthetic pyrimidine analogue with activity against hepatitis B virus (HBV). Intracellularly, clevudine is phosphorylated to its active metabolites, clevudine monophosphate and triphosphate. The triphosphate metabolite competes with thymidine for incorporation into viral DNA, thereby causing DNA chain termination and inhibiting the function of HBV DNA polymerase (reverse transcriptase). Clevudine has a long half-life and shows significant reduction of covalently closed circular DNA (cccDNA), therefore the patient is less likely to have a relapse after treatment is discontinued.

1. Neobavaisoflavone is isolated as a DNA polymerase inhibitor. 2. Neobavaisoflavone might be a potential anabolic agent to treat bone loss-associated diseases. 3. Neobavaisoflavone has anti-inflammatory activity, can significantly inhibit the production

Phytic acid dipotassium salt is an endogenous metabolite that inhibits β-secretase 1 (BACE1).

IMT1 (Propanamide, N,N-dimethyl-2-[[4-(2-methylphenyl)-2-oxo-2H-1-benzopyran-7-yl]oxy]-) has anticancer activity.

DNA polymerase-IN-1, a DNA polymerase inhibitor, exhibited antiproliferative activity against tumor cells with a half-inhibitory concentration (IC50) of 20.7 μM. DNA polymerase-IN-1 inhibited Taq DNA polymerase with an IC50 of less than 250 μM. DNA polymerase-IN-1 was shown to inhibit Taq DNA polymerase by RT- DNA polymerase-IN-1 showed antiretroviral activity in vitro by RT-PCR assay and can be used to study oxidative damage and colorectal cancer.

DNA polymerase-IN-6 (Compound 27) exhibits inhibitory activity against DNA polymerase, with EC50 values of 0.33 µM for HCMV, 1.9 µM for HSV-1, 0.76 µM for HSV-2, and 0.066 µM for EBV.

HCVNS5B polymerase-IN-2 (Compound 298) is an inhibitor of the Ns5b polymerase. It holds potential for research into the treatment of hepatitis C virus (HCV) infections.

RNA polymerase II-IN-1 (compound 19iv), an amatoxin, selectively inhibits RNA polymerase II (Pol II) with an IC50 of 36.66 nM and exhibits heightened cytotoxicity towards cancer cells while reducing toxicity in normal cells compared to α-Amanitin [1].

RNA polymerase II-IN-2 (compound 20iii), a potent inhibitor of RNA polymerase II (Pol II) with a K i value of 9.5 nM, exhibits cytotoxicity against cancer cells, demonstrating toxicity levels 2 and 5 times higher than α-amanitin in CHO and HEK293 cells, respectively [1].

Viral polymerase-IN-1 hydrochloride, a derivative of Gemcitabine, effectively inhibits influenza A and B virus infections with IC90 values between 11.4 and 15.9 μM, and shows activity against SARS-CoV-2 infection by interfering with viral RNA replication transcription within cells [1].

DNA polymerase-IN-2 (Compd 3c), a coumarin derivative, inhibits Taq DNA polymerase with an IC50 value of 48.25 μM and shows potential for value-added disease research [1].

DNA polymerase-IN-3 (Compd 5b), a coumarin derivative, inhibits Taq DNA polymerase and shows potential applications in proliferative disease research [1].

Taq DNA polymerase, a thermostable enzyme, is utilized in polymerase chain reactions (PCR) to amplify DNA sequences [1].

T7 RNA polymerase, expressed by Escherichia coli from the T7 bacteriophage RNA polymerase gene, is a highly specific enzyme utilized for in vitro transcription (IVT) of mRNA. This polymerase requires Mg 2+ and selects only DNA templates that contain the T7 promoter sequence, whether single-stranded or double-stranded. It employs NTPs to synthesize RNA that is complementary to the single-stranded DNA following the promoter [1] [2].

Poly(A) polymerase enzymatically adds a polyadenosine tail of 20-200 adenine bases to the 3' end of RNA, a process that involves integrating ATP as AMP. This modification enhances RNA stability and augments mRNA translation efficiency in eukaryotic cells, evidencing the enzyme's high tailing efficiency [1] [2].

DNA polymerase-IN-4 (Compd 5c), a coumarin derivative, demonstrates antiretroviral activity with an IC50 of 134.22 μM [1].

RNA polymerase-IN-1 (compound 4) acts as an inhibitor of DNA-dependent RNA polymerase. Additionally, it inhibits CYP isozymes [1].
