Epihetacillin is a derivative of Hetacillin. Epihetacillin can be obtained from hetacillin by treatment with triethylamine. Epi derivative is inactive. Hetacillin is a penicillin-like, beta-lactam-based antibiotic prodrug used to treat infections, usually from Gram-positive bacteria. Hetacillin itself has no antibacterial activity, but is converted in the body to ampicillin and has actions and uses similar to those of ampicillin. Hetacillin is prepared by reacting ampicillin with acetone. Ampicillin rapidly decomposes because of the intramolecular attack of the side chain amino group on the lactam ring. Hetacillin locks up the offending amino group and prevents the decompolsition Hetacillin, once hydrolyzed to ampicillin (and acetone) binds to the penicillin binding proteins found in susceptible bacteria. This inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins. Targets below reflect ampicillin targets. Hetacillin is sold under the trade name Hetacin for intramammary injection in veterinary use. Hetacillin was removed from the market for human use when the discovery was made that it is actually cleaved in the gastrointestinal tract to formaldehyde and had no advantages over ampicillin.

Cefathiamidine is a beta-lactam antibiotic that exhibits a broad spectrum of bactericidal activity against gram-positive bacteria. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

Patent Blue V (E-131) is a synthetic dye used as a food coloring. In Europe, it is used in beverages, preserves of red fruits, desserts, confectionary. In medicine, Patent Blue V is used as a contrast agent for visualizing lymphatic vessels. Patent Blue V is also used in dentistry in a disclosing tablet to demonstrate the presence of plaque on teeth.
Lappaconitine is an alkaloid isolated from the root of Aconltitum sinomantanum Nakai. It has a strong analgesic activity that does not involve the opioid receptor. It was shown to have class-I antiarrhythmic action and irreversibly blocks cloned human heart (hH1) channels by binding to the site 2 receptor.

Tebipenem pivoxil is an oral carbapenem prodrug that was originated by Wyeth (now Pfizer). It was approved by Pharmaceuticals and Medical Devices Agency of Japan (PMDA) on Apr 22, 2009. It was developed and marketed as Orapenem® by Meiji Seika in Japan. Tebipenem pivoxil is a broad-spectrum orally-administered antibiotic, from the carbapenem subgroup of β-lactam antibiotics. Carbapenems are a class of beta-lactam antibiotics, which act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. It is used to treat otorhinolaryngological infection, otitis media and bacterial pneumonia. Orapenem® is available as granules for oral use, containing 100 mg Tebipenem pivoxil/g granules. According to the weight of children, 4 mg/kg, and twice a day after dinner.
Midecamycin diacetate (a derivative of Midecamycin) is reported as an ingredient of Miocamycin in Japan. Miocamycin is an orally administered 16-membered macrolide antimicrobial drug. It has a spectrum of in vitro activity similar to that of erythromycin, inhibiting a range of Gram-positive and Gram-negative organisms, atypical microbes and some anaerobes. Importantly, miocamycin demonstrates greater in vitro potency than erythromycin against several pathogens including Legionella pneumophila, Mycoplasma hominis, and Ureaplasma urealyticum. Equally noteworthy is its activity against erythromycin-resistant staphylococcal and streptococcal species expressing inducible-type resistance. Miocamycin possesses poor overall activity against Haemophilus influenzae and is inactive against Enterobacteriaceae. Penetration of miocamycin into body tissues and fluids is both rapid and extensive. The 3 major metabolites of miocamycin possess antimicrobial activity and may contribute to the therapeutic efficacy of the drug. Clinical data indicate that miocamycin is useful in the treatment of upper and lower respiratory tract infections in both adult and paediatric patients. Miocamycin is also effective in the treatment of urogenital tract infections caused by Chlamydia trachomatis or U. urealyticum. Midecamycin binds reversibly to 50S ribosomal subunit causing blockade of transpeptidation/translocation reactions, inhibition of protein synthesis and thus inhibition of cell growth. Midecamycin diacetate is also known as MIOCAMEN, Merced Box of 8 sachets (900mg), Mosil, Myoxam.
Sultamicillin is the mutual prodrug of sulbactam and ampicillin. It is the tosylate salt of the double ester of sulbactam plus ampicillin. Sulbactam is a semisynthetic ß-lactamase inhibitor which, in combination with ampicillin, extends the antibacterial activity of the latter to include some ß-lactamase-producing strains of bacteria that would otherwise be resistant. The combination of sulbactam plus ampicillin for parenteral use has previously been shown to be clinically and bacteriologically effective in a variety of infections. Sultamicillin is marketed under a trade name Unasyn among others.
Midecamycin (Acetate) is a macrolide antibiotic with actions and uses similar to those of erythromycin but somewhat less active. It is synthesized from Streptomyces mycarofaciens. It has been given by mouth to treat variety of bacterial infections like respiratory tract, ear, skin infections etc. Antibiotics require constant drug level in body for therapeutic effect. This is achieved by taking the drug at regular interval of time throughout the day and night as prescribed. Midecamycin (Acetate) is primarily indicated in conditions like Bronchitis, Laryngopharyngitis, Otitis media, Periodontitis, Pneumonia, Respiratory tract infections, Skin infections, Subcutaneous abscess, Tonsillitis. Midecamycin inhibits bacterial growth by targeting the 50S ribosomal subunit preventing peptide bond formation and translocation during protein synthesis. Resistance to midecamycin is commonly attributed to mutations in 50S rRNA preventing midecamycin binding allowing the cell to synthesize proteins free of error.
