Penciclovir (BRL 39123) is a Herpesvirus Nucleoside Analog DNA Polymerase Inhibitor. In HSV infected cells, penciclovir is phosphorylated by viral thymidine kinase and subsequently converted by cellular kinases into the active metabolite, penciclovir triphosphate, which competitively inhibits viral HSV polymerase by blocking deoxyguanosine triphosphate substrate binding. As a result, herpes viral DNA synthesis and replication are selectively inhibited.

Zoliprofen is 20 times more effective than ibuprofen and fenoprofen against collagen- or arachidonic acid-induced platelet aggregation in rats and rabbits. Zoliprofen was 20 times more effective than ibuprofen and fenoprofen in inhibiting endotoxin-induced diarrhoea in mice and arachidonic acid-induced acute mortality in rabbits.

Benzthiazide (Lemazide) is used in the therapy of edema and hypertension. Like other thiazides, benzthiazide accelerates water loss from the body (diuretics). They inhibit Na+/Cl- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium and an increase in serum uric acid. Thiazides are often used to treat hypertension, but their hypotensive effects are not necessarily due to their diuretic activity. Thiazides have been shown to prevent hypertension-related morbidity and mortality although the mechanism is not fully understood. Thiazides cause vasodilation by activating calcium-activated potassium channels (large conductance) in vascular smooth muscles and inhibiting various carbonic anhydrases in vascular tissue.

Imiprothrin is an inducer of CYP1A2 and metallothionein 1a, exhibiting significant genotoxicity and cytotoxicity. In rat hepatocytes, it triggers detoxification responses by upregulating these genes. Imiprothrin induces chromosomal aberrations and micronucleus formation in rat bone marrow and causes DNA damage in liver cells. It leads to oxidative stress in rats, resulting in lipid peroxidation, excessive reactive oxygen species, and redox imbalance, subsequently impairing liver and kidney function and causing tissue damage. Imiprothrin inhibits weight gain in mice and, at high doses, significantly increases mortality in female mice. However, it shows no carcinogenic properties in rat studies, where aspartate aminotransferase and total protein are identified as sensitive toxicity biomarkers.
