Gemfibrozil (CI-719) interacts with peroxisome proliferator-activated receptors (PPARalpha) resulting in PPARalpha-mediated stimulation of fatty acid oxidation and an increase in lipoprotein lipase (LPL) synthesis. Gemfibrozil is a fibric acid derivative with hypolipidemic effects. This enhances triglyceride-rich lipoprotein clearance and reduces the expression of apolipoprotein C-III (apoC-III). The reduction in hepatic production of apoC-III result in the subsequent reduction of serum levels of very-low-density-lipoprotein cholesterol (VLDL-C). In addition, gemfibrozil-mediated PPARalpha stimulation of apoA-I and apoA-II expression results in an increase in high-density lipoprotein cholesterol (HDL-C).

Ambroxol (NA-872) is a secretolytic agent used in the treatment of respiratory diseases associated with viscid or excessive mucus. It is the active ingredient of Mucosolvan, Lasolvan or Mucoangin. The substance is a mucoactive drug with several properties including secretolytic and secretomotoric actions that restore the physiological clearance mechanisms of the respiratory tract which play an important role in the body's natural defense mechanisms. It stimulates synthesis and release of surfactant by type II pneumocytes. Surfactants act as an anti-glue factor by reducing the adhesion of mucus to the bronchial wall, in improving its transport and in providing protection against infection and irritating agents.

MK-8245 trifluoroacetate is a phenoxy piperidine isoxazole derivative functioning as a potent, liver-targeting stearoyl-CoA desaturase (SCD) inhibitor, demonstrating significant anti-diabetic and anti-dyslipidemic effects. It showcases high specificity and efficacy against SCD1 across various species, with IC50 values of 1 nM for human SCD1 and 3 nM for both rat and mouse SCD1. MK-8245's mechanism includes a tetrazole acetic acid moiety that facilitates liver-targeting through OATPs recognition. Its inhibition potency in rat hepatocyte assays (IC50 of 68 nM) surpasses that in HepG2 cell assays devoid of active OATPs (IC50 of ~1 μM), highlighting its liver specificity. Moreover, MK-8245 exhibits over 100,000-fold selectivity against Δ-5 and Δ-6 desaturases in comparative assays. In vivo studies reveal MK-8245's preferential liver distribution in mice, rats, dogs, and rhesus monkeys, underscoring its potential for minimizing adverse effects in non-target tissues. Additionally, its administration in eDIO mice before glucose challenges significantly improves glucose clearance, indicating its therapeutic promise in diabetes management.

Paromomycin (Sulfate Salt) is an aminoglycoside that is active against Gram-negative and many Gram-positive bacteria as well as some protozoa and cestodes. Paromomycin in combination with sodium stibogluconate has proven to be effective in African and Indian VL (visceral leishmaniasis) and improves survival in African VL[3]. PS (Paromomycin Sulfate) is effective for elimination of B. coli without hematological side effects[4]. The activity of phosphoglucose isomerase was slightly inhibited by 10(-3) M paromomycin sulfate while those of hexokinase, phosphofructokinase and glucose-6-phosphate dehydrogenase were not inhibited[5]. In addition, with regard to correlation of endotoxemia with renal impairment, endogenous creatinine clearance and p-aminohippurate clearance were significantly improved (P less than 0.02) in those patients whose endotoxemia disappeared on paromomycin sulfate administration. Paromomycin sulfate seems to be effective in the prevention of endotoxemia and the associated renal impairment in cirrhosis in man[6]. Significantly higher frequencies of resistance to paromomycin, kanamycin, neomycin and tobramycin were observed in S. aureus isolates from PS (paromomycin supplemented) birds. Paromomycin supplementation resulted in resistance to aminoglycosides in bacteria of PS turkeys. Co-selection for resistance to other antimicrobial agents was observed in E. coli isolates[7].

Valganciclovir, the L-valyl ester of ganciclovir, is a prodrug effectively converted to ganciclovir in the body, serving as an antiviral medication for cytomegalovirus (CMV) infections. In vitro studies demonstrate that valganciclovir inhibits glycylsarcosine transport mediated by PEPT1 and PEPT2 in Caco-2 and SKPT cells, respectively, with competitive inhibition K(i) values of 1.68±0.30 mM for PEPT1 and 0.043±0.005 mM for PEPT2. Clinical trials indicate valganciclovir's non-inferior efficacy to ganciclovir in pre-emptive therapy for CMV, exhibiting no significant difference in viral clearance rates or toxicity levels between the treatments. Specifically, 89.5% of patients treated with valganciclovir and 83% treated with ganciclovir achieved viral clearance at 28 days (P=0.030 for non-inferiority). Additionally, valganciclovir prophylaxis at 450 mg twice daily prevented CMV reactivation in patients on an alemtuzumab-containing regimen, with none of the 20 patients experiencing reactivation (P=0.004).
