Antibiotic resistance is a major global concern that primarily affects public health. Texiobactin is a newly discovered antibiotic produces by soil microbes isolated from natural environment. Drug is active against Gram-positive bacteria as it inhibits biosynthesis of peptidoglycan. Infection of methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae in mice elicits a good response reduce bacterial load. Although extensive efforts have been made to discover new antibiotics but results are still not satisfactory to meet the demands of public health. Recently it has been shown that the discovery of texiobactin by iChip will be a great stone mile to discover more antibiotics.

Environmental pollution is a major global problem that affects human health. Among different types of environmental pollution, particulate matter (PM) has a key role. As PM spreads in the air so it causes different bronchial and skin inflammatory conditions. PM increases oxidative stress by ROS production and pro-inflammatory cytokines. As a result, matrix metalloproteinase is also produced, such as MMP1, MMP9 and MMP2 that is a known major cause of skin collagen degradation. Recently it has been shown that the PM worsens allergic conditions like dermatitis, psoriasis, and skin cancer. Different extensive efforts have been made across the globe to control this PM.

Inflammation is a biological response caused by overactivation of the immune system and is controlled by immune cells via a variety of cytokines. The overproduction of pro-inflammatory cytokines enhances abnormal host immunity, resulting in diseases such as rheumatoid arthritis, cardiovascular disease, Alzheimer's disease, and cancer. Inhibiting the production of pro-inflammatory cytokines such as interleukin (IL)-12p40, IL-6, and tumor necrosis factor (TNF)-α might be one way to treat these conditions. Here, we investigated the anti-inflammatory activity of compounds isolated from Cimicifuga dahurica (Turcz.) Maxim., which is traditionally used as an antipyretic and analgesic in Korea. In primary cell culture assays, 12 compounds were found to inhibit the production of pro-inflammatory cytokines (IL-12p40, IL-6, and TNF-α) in vitro in bone marrow-derived dendritic cells stimulated with LPS.
