描述

碘化钾是一种无机化合物，化学式为 KI。它是一种金属卤化盐，钾阳离子 (K⁺) 和碘阴离子 (I⁻) 之间形成离子键。该化合物呈现无色至白色立方晶体、粉末或白色颗粒。碘化钾广泛应用于医药、辐射防护以及作为膳食补充剂 .

作用机制

碘化钾主要作用于甲状腺。它抑制甲状腺激素的合成和释放，降低甲状腺血管性，并增加甲状腺滤泡中胶体的积累。这导致甲状腺变硬，细胞尺寸减小，结合碘水平升高。此外，碘化钾阻止放射性碘被甲状腺吸收，从而降低辐射照射期间患甲状腺癌的风险 .

类似化合物：

碘酸钾 (KIO₃)： 用作食盐中的碘补充剂，并在辐射事故中用于阻断甲状腺。

碘化钠 (NaI)： 在与碘化钾类似的应用中使用，但溶解度和反应性不同。

碘化钙 (CaI₂)： 用于动物饲料以及作为各种应用中的碘源

碘化钾的独特性： 碘化钾的独特之处在于它在水中的高溶解度，使其成为各种化学和生物应用中碘离子的有效来源。它能够保护甲状腺免受放射性碘的伤害以及在碘量法滴定中的应用进一步突出了它的多功能性和重要性 .

Mechanism of Action	In hyperthyroid patients, potassium iodide produces rapid remission of symptoms by inhibiting the release of thyroid hormone into the circulation. The effects of potassium iodide on the thyroid gland include reduction of vascularity, a firming of the glandular tissue, shrinkage of the size of individual cells, reaccumulation of colloid in the follicles, and increases in bound iodine. These actions may facilitate thyroidectomy when the medication is given prior to surgery., When administered prior to and following administration of radioactive isotopes and in radiation emergencies involving the release of radioactive iodine, potassium iodide protects the thyroid gland by blocking the thyroidal uptake of radioactive isotopes of iodine., The mechanism of action of potassium iodide's antifungal activity against Sporothix schenckii has not been determined. Potassium iodide does not appear to increase monocyte or neutrophil killing of S. schenckii in in vitro studies. However, exposure of the yeast form of S. schenckii to various concentrations of iodine (iodine and potassium iodide solution) has resulted in rapid cell destruction., Potassium iodide is thought to act as an expectorant by increasing respiratory tract secretions and thereby decreasing the viscosity of mucous ..., When potassium iodide is administered simultaneously with radiation exposure, the protectant effect is approximately 97%. Potassium iodide given 12 and 24 hours before exposure yields a 90% and 70% protectant effect, respectively. However, potassium iodide administered 1 and 3 hours after exposure results in an 85% and 50% protectant effect, respectively. Potassium iodide administered more than 6 hours after exposure is thought to have a negligible protectant effect.	Source

Q & A

Q1: How does potassium iodide interact with the thyroid gland?

A1: this compound provides the essential nutrient iodine, which the thyroid gland actively absorbs to produce the hormones thyroxine (T4) and triiodothyronine (T3). In situations of radioactive iodine exposure, this compound saturates the thyroid with stable iodine, blocking the uptake of the radioactive form and reducing the risk of thyroid cancer. []

Q2: Can this compound induce hyperthyroidism?

A2: Yes, in some cases, particularly in individuals with pre-existing thyroid conditions or those sensitive to iodine, this compound administration can lead to hyperthyroidism. This was observed in three geriatric patients receiving this compound during a 125I-fibrinogen test. []

Q3: What are the recommended daily allowances for iodine intake?

A3: The recommended daily allowances (RDA) for iodine intake are 150 μg in adults, 220–250 μg in pregnant women, and 250–290 μg in breastfeeding women. [] The American Thyroid Association (ATA) recommends that women take a multivitamin containing 150 μg of iodine daily in the form of this compound (KI) during preconception, pregnancy, and lactation to meet these needs. []

Q4: What is the effect of this compound on cathepsins in rat thyroid cells?

A6: Research using the FRTL thyroid cell line shows that high concentrations of this compound (50 mmol/L) significantly decrease the activity of cathepsins B and D. These enzymes play a role in thyroid hormone synthesis and release, suggesting iodine excess might affect thyroid function through this mechanism. []

Q5: What is the molecular formula and weight of this compound?

A5: The molecular formula of this compound is KI, and its molecular weight is 166.00 g/mol.

Q6: Can this compound be used as a photostabilizer?

A9: Yes, this compound solutions, which tend to turn yellow upon light exposure due to iodine liberation, can be stabilized using compounds like DL-methionine and thiourea. These compounds prevent color change even under intense light exposure for extended periods. []

Q7: How does this compound function as a catalyst?

A11: this compound can act as a catalyst in various reactions. For instance, it catalyzes the synthesis of 1,3-dioxolan-2-one derivatives from epoxides and carbon dioxide, even at relatively low temperatures (60°C). []

Q8: Is this compound truly a catalyst in the decomposition of hydrogen peroxide?

A12: Contrary to common belief, experimental evidence suggests that this compound is not a true catalyst in hydrogen peroxide decomposition. While it accelerates the reaction, it also undergoes chemical changes, as evidenced by the solution turning yellow due to iodine formation and changes in pH, conductivity, and iodide ion concentration. []

Q9: Can this compound be used in conjunction with biomass for CO2 conversion?

A13: Yes, research shows that dewaxed sugarcane bagasse combined with this compound can act as an effective catalytic system for converting CO2 to cyclic carbonates. The hydroxyl groups in the biomass play a crucial role in this process by activating the epoxide ring opening. []

Q10: Have computational methods been used to study this compound?

A14: Yes, molecular beam scattering data has been used to create highly accurate excited-state potential energy surfaces for this compound, furthering the understanding of its spectroscopic properties and behavior in excited states. []

Q11: Does the counterion to iodide affect iodine absorption?

A15: Yes, studies comparing this compound (KI) and sodium iodide (NaI) in rabbits showed that KI resulted in peak blood iodine levels being maintained for a longer duration compared to NaI. This suggests that the counterion can influence the pharmacokinetics of iodide. []

Q12: How can the stability of this compound formulations be improved?

A16: this compound jellied pharmaceutical compositions have been developed to improve storage stability and dissolution, allowing for easier medication. These formulations typically include gelling agents and dispersion media to achieve the desired properties. []

Q13: How is iodine absorbed and distributed in the body after this compound administration?

A17: Following oral administration, this compound is readily absorbed in the gastrointestinal tract. Iodine is then distributed throughout the body, with the thyroid gland actively accumulating it for hormone synthesis. Excess iodine is primarily excreted in urine. []

Q14: How does the absorption of iodine from this compound compare to that of iodine from kombu?

A18: Studies in rats have shown that the absorption of iodine from this compound is significantly higher compared to iodine from kombu, a type of seaweed. This difference was observed by comparing serum and tissue iodine concentrations in rats fed diets supplemented with either this compound or kombu powder. []

Q15: Can this compound be used to treat haemoptysis caused by aspergillomas?

A19: Yes, in cases where surgery is not an option, intracavitary instillation of sodium or this compound has been shown to be effective in stopping life-threatening haemoptysis from aspergillomas. []

Q16: What are the potential risks of excess iodine ingestion?

A20: Ingesting iodine in amounts exceeding the tolerable upper limits (1100 μg per day) can lead to thyroid dysfunction, particularly in susceptible individuals like infants, pregnant and breastfeeding women, the elderly, and those with pre-existing thyroid conditions. [] High iodine intake can cause effects ranging from goiter to hypothyroidism or hyperthyroidism. []

Q17: What analytical methods are used to determine iodide levels?

A21: Several methods are available for determining iodide levels, including volumetric titration methods like the Sadusk-Ball procedure, which is particularly useful for analyzing iodized salt. [] Other methods might include ion chromatography or spectrophotometry after appropriate chemical derivatization.
