Antimicrobiens

Inhibitor of protein synthesis; aminoglycoside

Penciclovir is an antiviral agent and acyclic guanine derivative that has proven efficient in the treatment of Herpes Simplex type 1 and 2 (HSV1 and HSV2) infection. Penciclovir is transformed by the virus into an active derivative able to block the deoxyguanosine triphosphate substrate binding site of the HSV polymerase.

Gentamicin C2a sulfate is one epimeric form of the aminoglycoside antibiotic gentamicin (a.k.a. gentamycin). Gentamicin interferes with the correct protein production in bacterial cells, by binding to the 16s rRNA at the 30s ribosomal subunit. Gentamicin is a natural mixture of four congeners, one of which is gentamicin C2a. Gentamicin is active against clinically relevant aerobic gram-negative bacteria. Gentamicin C2a has been shown to be biodegradable in the environment, to some extent.

Raltegravir is an antiretroviral agent used for the treatment of HIV infections in conjunction with other antiretrovirals. It inhibits the activity of HIV-1 integrase, which impedes the insertion of HIV-1 DNA into the host cell genome. Raltegravir also inhibits resistant mutants of HIV-1 that are associated with disease activity and progression.

Nucleoside analog with antiviral activity against coronaviruses, hepatitis and influenzas viruses. EIDD 1931 inhibited the Middle East Respiratory Syndrome coronavirus (MERS-CoV) and the murine hepatitis virus (MHV) replication in vitro at submicromolar concentrations. EIDD 1931 is able to evade the proofreading exonuclease ExoN and presents with high barrier to development of drug resistance.

Inhibitor of cell-wall synthesis; carbapenem class

Ribostamycin sulphate is an aminoglycoside antibiotic with action on bacterial protein synthesis by binding to the 30S ribosomal subunit and is used for treating bacterial infections like sepsis and pneumonia.

Inhibitor of protein synthesis; steroid antibiotic

5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate is an antibacterial compound with a broad spectrum of activity against Gram-positive and Gram-negative bacteria. It is active against strains resistant to other antibiotics, such as, tetracycline and penicillin. 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate has been shown to be effective in vitro against Campylobacter jejuni - the most common cause of bacterial gastroenteritis in humans. The compound also inhibits the growth cycle of Campylobacter jejuni by arresting the cells at the G1 phase. The molecule has been shown to inhibit DNA synthesis in E. coli and S. typhimurium with IC50 values of 1 ÎŒM and 0.8 ÎŒM respectively. This molecule has been tested for its surface active properties and it can be used as an additive in personal care products for improved wetting and spreading on surfaces. The compound is also researched for its antifungal efficacy against Candida albicans by inhibiting the growth cycle of the fungus.

Filociclovir is a novel antiviral agent, which is synthesized from small-molecule pharmaceutical compounds. It functions primarily by inhibiting viral DNA polymerase, thereby halting viral replication within infected host cells. This mechanism of action is particularly effective against certain herpesviruses, as it targets the polymerase enzyme that is critical for viral DNA synthesis and proliferation.

Chlorotetracycline monohydrochloride is an antibiotic designed for culture media use. It is derived from the bacterium *Streptomyces aureofaciens*, and functions primarily by inhibiting bacterial protein synthesis. This action prevents the attachment of aminoacyl-tRNA to the ribosomal acceptor site, effectively halting the growth of bacteria by disrupting protein production, which is essential for their survival and replication.
