Oritavancin diphosphate (LY333328 diphosphate) 是一种新型半合成的糖肽抗生素, 可研究革兰氏阳性菌感染。

Tebipenem Pivoxil (Orapenem) 是一种碳青霉烯类新型口服抗生素。

Cefuroxime (Cephuroxime) 是一种具有口服活性的第二代头孢菌素类抗生素，具有抗菌活性，抑制革兰氏阳性菌和革兰氏阴性菌，可用于研究软组织感染。

Ceftaroline fosamil hydrate acetate 是一种高效的头孢菌素类抗生素(antibiotic)，对多种病原体有广谱活性，特别是针对革兰氏阳性病原体，如耐甲氧西林金黄色葡萄球菌(MRSA)和耐多药肺炎链球菌，以及常见的革兰氏阴性微生物。此外，Ceftaroline fosamil hydrate acetate 在治疗复杂皮肤及皮肤结构感染(cSSSIs)和社区获得性肺炎(CABP)方面表现出显著的抗感染活性。

Plectasin, 一种源自腐生真菌的肽类抗生素 (antibiotic)，能够有效杀灭体外的肺炎链球菌，并可减轻小鼠体内因肺炎链球菌导致的实验性腹膜炎和肺炎症状。

Grepafloxacin (OPC-17116) is a fluoroquinolone antibiotic that is administered orally. It possesses strong efficacy against community-acquired respiratory pathogens, notably Streptococcus pneumonia. Grepafloxacin exhibits excellent tissue penetration and demonstrates a promising pharmacodynamic profile.

Gemifloxacin mesylate (Gemifloxacin mesylate) 是一种喹诺酮类口服广谱抗菌剂，可研究轻中度肺炎和慢性支气管炎的急性细菌性发作。

Nafithromycin (WCK 4873) 作为一种口服抗生素 (antibiotic)，主要用于治疗由肺炎链球菌、流感嗜血杆菌、卡他莫拉菌及Methicillin敏感金黄色葡萄球菌引发的社区获得性肺炎。该药物对于大环内酯耐药以及对Telithromycin不敏感的肺炎链球菌，具有较低的最小抑菌浓度（MIC90），仅为0.12 mg liter。

Omadacycline, also known as PTK 0796 and Amadacyclin, is a novel first-in-class aminomethylcycline with potent activity against important skin and pneumonia pathogens, including community-acquired methicillin-resistant Staphylococcus aureus (MRSA), β-hemolytic streptococci, penicillin-resistant Streptococcus pneumoniae, Haemophilus influenzae, and Legionella. Omadacycline is active against strains expressing the two main forms of tetracycline resistance (efflux and ribosomal protection). The primary effect of omadacycline is on bacterial protein synthesis, inhibiting protein synthesis with a potency greater than that of tetracycline. The binding site for omadacycline is similar to that for tetracycline.
