Carbon Tetrafluoride
Tetrafluoromethane, also known as carbon tetrafluoride, is colorless, tasteless and odorless. Insoluble in water, 0.0015 at 25 ℃ under normal pressure, soluble in chloroform and benzene. This product is non-toxic and non combustible. High concentration has anesthetic effect. The high-purity gas and its mixture with high-purity oxygen are the most widely used plasma etching gas in microelectronics industry, and can also be used as low-temperature refrigerant and insulation medium. It is inert to many reagents and does not hydrolyze at 1000 ℃. It does not react with copper, nickel and tungsten at room temperature. Because of the strong chemical stability of the C-F bond, the perfluorocarbons represented by CF4 can be considered to be basically nontoxic.
Carboplatin
Carboplatin is the second generation of platinum antitumor drugs. Its antitumor activity is similar to cisplatin, but its nephrotoxicity, ototoxicity and neurotoxicity, especially gastrointestinal reaction, are significantly lower than cisplatin, and its antitumor spectrum is not as wide as cisplatin. The main mechanism of action is to cause cross-linking between and within DNA chains, interfere with DNA molecules and inhibit DNA synthesis of cells. It mainly acts on N-7 and O-6 atoms of guanine in DNA and produces cytotoxic effect. Because the cyclobutane ring in carboplatin molecule is more stable as a ligand than the chloride ion group in cisplatin, it was initially thought that carboplatin may not have the ototoxicity, nephrotoxicity and neurotoxicity like cisplatin, but it has been proved by systematic biological evaluation and a large number of clinical trials, Although carboplatin is not as serious as cisplatin in renal toxicity, myelosuppression, ototoxicity and neurotoxicity, its damage to the body can not be ignored. There is cross resistance between cisplatin and its antitumor effect in vivo, so cancer cells that are not sensitive to cisplatin are also resistant to cisplatin. It was found that carboplatin not only inhibited tumor growth, but also had radiosensitization effect.
Carrageen
Carrageenan is a family of linear sulfated polysaccharides that are extracted from red edible seaweeds. They are widely used in the food industry, for their gelling, thickening, and stabilizing properties.

Sildenab can inhibit VEGF induced angiogenesis, neovascularization and xenograft cell growth. In the phase I study of NSCLC patients, it was found that the combination of sildenab and PC regimen had significant antitumor effect. Phase II / III study br24 studied 30 mg of sildenab as the first-line treatment for NSCLC patients, which proved that it had antitumor effect, but the incidence of adverse events was high, including diarrhea, dehydration, hand foot syndrome, hypertension and neutropenia. Therefore, it was decided to stop the clinical trial. Repeated evaluation of the dose and toxicity of the combination indicated that part of the adverse reactions were dose-related, and it could be tried to reduce the dose to improve the drug tolerance.
Cefazolin
Cefazolin (INN), also known as cefazoline or cephazolin is an antibiotic useful for the treatment of a number of bacterial infections.It is a first-generation cephalosporin antibiotic. Cephalosporins fall into the category of β-Lactam (beta-lactam) antibiotics. Other antibiotics that fall into this category are penicillin derivatives, monobactams and carbapenems. This group of antibiotics works by inhibiting cell wall synthesis of the bacteria by binding to penicillin-binding proteins. These groups of antibiotics are known as bactericidal, meaning that they kill the targeted bacteria (as opposed to inhibiting reproduction as bacteriostatic antibiotics do).

Chlorimuron-ethyl is a kind of post-emergence, foliar applied herbicide which is used without the EU regulatory approval. As an herbicide belonging to the sulfonylurea family, it is commonly used to control the weeds associated with wheat, rice, soybean, barley, potato, and corn. It has advantages of being broad-spectrum, having low use rate, having good crop selectivity as well as being of low toxicity to animals. Its mechanism of action is through suppressing the plant- and microbial-specific enzyme acetolactate synthase (ALS), further blocking the biosynthesis of branched-chain amino acids such as valine, leucine and isoleucine. Through this mechanism, it cause rapid cessation of plant cell division and growth.
Chlorine Dioxide
Red and yellow have strong irritating odor gas: liquefy into red brown liquid at 11 ℃ , and solidify into orange red crystal at - 59 ℃ . It has a special odor like chlorine and nitric acid.
