Up to [●] Placement Agent Warrants to Purchase up to [●] Shares of Common Stock

Up to [●] Shares of Common Stock underlying the Prefunded Warrants, Series C Warrants, Series D Warrants and

We are offering up to [●] shares of common stock, together with Series C warrants to purchase up to [●] shares of common stock (the “Series C Warrants”) and Series D warrants to purchase up to [●] shares of common stock (the “Series D Warrants”), which we refer to collectively as the “common warrants,” at an assumed combined public offering price of $[●] per share and common warrants, which is equal to the last reported sale price per share of our common stock on The Nasdaq Capital Market, on December [●], 2024 (and the shares issuable from time to time upon exercise of the common warrants) pursuant to this prospectus. The shares of common stock and common warrants will be separately issued, but the shares of common stock and common warrants will be issued to purchasers in the ratio of one-to-one. Each common warrant will have an exercise price of $[●] per share (100% of the combined public offering price) and will be exercisable beginning on the effective date of stockholder approval of the issuance of the shares upon exercise of the common warrants (“Warrant Stockholder Approval”), provided, however, that, if and only if the Pricing Conditions (as defined below) are met, the common warrants will be exercisable upon issuance. As used herein “Pricing Conditions” means that the combined offering price per share and accompanying common warrants is such that the Warrant Stockholder Approval is not required under the rules of the Nasdaq Stock Market LLC (“Nasdaq”) because either (i) the offering is an at-the-market offering under Nasdaq rules and such price equals or exceeds the sum of (a) the applicable “Minimum Price” per share under Nasdaq Rule 5635(d) plus (b) $0.125 per whole share of common stock underlying the common warrants or (ii) the offering is a discounted offering where the pricing and discount (including attributing a value of $0.125 per whole share underlying the common warrants) meet the pricing requirements under Nasdaq’s rules. The Series C Warrants will expire [●] years from the initial exercise date. The Series D Warrants will expire [●] years from the initial exercise date. This is a “best efforts” offering and we may sell fewer than all of the shares of common stock, common warrants and pre-funded warrants offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund if we do not sell all of the securities offered hereby.

We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded warrants to purchase up to [●] shares of common stock, in lieu of shares of common stock that would otherwise result in such purchaser’s beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The purchase price of each pre-funded warrant and related common warrants will be equal to the public offering price for the common stock and related common warrants in this offering, minus $0.001. Each pre-funded warrant is exercisable for one share of our common stock and has an exercise price of $0.001 per share. For each pre-funded warrant that we sell, the number of shares of common stock we are offering will be reduced on a one-for-one basis.

There is no established public trading market for the pre-funded warrants or common warrants, and we do not expect a market to develop. We do not intend to apply for listing of the pre-funded warrants or common warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the pre-funded warrants and common warrants will be limited.

This offering will terminate on [●], 2025, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or pre-funded warrant) and common warrants will be fixed for the duration of this offering.

We have engaged [●] to act as our exclusive placement agent (the “placement agent”) in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum number of securities or minimum aggregate amount of proceeds that is a condition for this offering to close. We may sell fewer than all of the shares of common stock, common warrants and pre-funded warrants offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund if we do not sell all of the securities offered hereby. Because there is no escrow account and no minimum number of securities or amount of proceeds, investors could be in a position where they have invested in us, but we have not raised sufficient proceeds in this offering to adequately fund the intended uses of the proceeds as described in this prospectus. We will bear all costs associated with the offering. See “Plan of Distribution” on page [●] of this prospectus for more information regarding these arrangements.

Our common stock is listed on The Nasdaq Capital Market, or Nasdaq, under the symbol “MBRX”. The last reported sale price of our common stock on Nasdaq on December [●], 2024 was $[●] per share. We do not intend to list the common warrants or pre-funded warrants on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system.

The actual public offering price per share and common warrants and the actual public offering price per pre-funded warrant and common warrants will be determined between us, the placement agent and the investors based on market conditions at the time of pricing, and may be at a discount to the current market price of our common stock.
